Ah, pity I wasn't reading the forums back in February. I'm fond of that game, along with Bugbear's other early title, Rally Trophy. I was never too good at FlatOut, but it was always a hoot to play.

When talking about a possible libre version of TDM (https://forums.thedarkmod.com/index.php?/topic/22346-libre-version-of-tdm/) it seems we believe all media/gamedata included in TDM is licensed CC-BY-NC-SA. I am not familiar with how the process of adding new media/gamedata works today; I have seen files uploaded to the bugtracker which developers then commit to SVN, but I don't know if there are other ways. It may be a good idea to implement a process that when new components (media/gamedata included in TDM) are added, the contributor is asked to be explicit about the license (a choice which may defaults to their previous preference, for usability). It won't fix the past, but it may help in the future. This will make it easy for contributors to add future data under a more permissive license if they choose. Libre media can be added and its license can be tracked, rather than assumed to be CC-BY-NC-SA. I suggest looking at how Wikimedia Commons has implemented this: the contributor state the source and license at the time the data is uploaded. This can be done either by providing urls or by saying "It's my work and I choose this licsense". The first step could be to add a way to keep track of each filepath in SVN, author, license, sources. Start by setting the value for each file's license to "(default/legacy CC-BY-NC-SA)". Possible implementations for a user interface for new additions are: * Use our own wiki, which runs Mediawiki (same as Wikimedia Commons). I see several benefits of this, but we also need a way to accept uploads of batches, not just single files. * Look at how other open source projects have solved this. There may be more appropriate solutions available. ... but I'll leave the implementation open. Suggestions are very welcome! If the author of each file already in SVN can be tracked, then it may be possible that the author is willing to give a blanket permission for all their past files in one statement, and all their files in SVN can be updated in one commit. A productive contributor willing to release some of their work under a more permissive license could make a big change. If Dark Radiant would support letting mappers search media/gamedata by license (does it already?), it would make it easier for mappers to create a completely libre mission, which would help facilitate a TDM-libre release. If I understand things correctly. This post does not address all details and it may contain misunderstandings or assumptions, but it's a start. Also relevant: * Is there a compiled and maintained list of recommended or deprecated resources for mappers to use? * https://forums.thedarkmod.com/index.php?/topic/20311-external-art-assets-licensing/

They don't work with stencil shadows. If a player has stencil shadows enabled, the volumetric lights have forced shadow maps enabled, while other lights have still stencil shadows. So it will just work. I think it will have a performance hit (also because the mentioned forced shadow maps I assume), but the mission overal is not very demanding? Afaik volumetric lights is enabled with a spawnarg. So via a trigger/script this setting can be changed? Not sure.

I think it's ok to include shadow maps features as long as fms don't become depended on it. Meaning you can't play it properly with stencil shadows enabled.

Type of mission: Mansion/Estate/Horror Story: Lord Blackgrove recently purchased a rare expensive artifact. The whole family has now disappeared leaving the manor empty. Time to check out the manor and see if the artifact can be found. Build time: My first map ever, 300 hours (5 months).

Be sure to set TDM Object Details (LOD) to Normal (or lower) to take advantage of some of the optimizations. Edit: Version 1.03 further improves performance around hedges thanks to HMart's alternative hedge model. I’ve had a mission like this in mind for years.

I'll add one thing, which I didn't state earlier because I assumed it was obvious. But I'd like to make it clear. What is the purpose of dragging a body and body manipulation in this stealth game? In my opinion, it is a "tool" or "game mechanic" that gives the player the ability to do two things: The last 10%. After shouldering a body and dropping it in a desired location, the player can drag and hide it more precisely in the shadows. Is just a foot or hand sticking out into the light? No problem. Grab and drag it into the shadows. No need to shoulder and drop the entire body again. That's a good thing. Dragging gives fine-tuned control for that scenario. Nearby shadows. After KO-ing a guard near a dark area, the player can quickly drag the guard into the dark area. The distance here would be one or two body lengths away. Given that the distance is short, dragging is quicker than shouldering and dropping. That's a good thing. Dragging gives a quick way to hide a body in that scenario. In my opinion, the 2.12 controls enhance the experience for those two scenarios, because the controls give a quick way to grab a body, drag it into position, and release it quickly and precisely. However, most of the time that fine-tuned control is not necessary for this stealth game. Shouldering and dropping a body can work well enough, hence why it became the primary action. That said, being able to precisely drag a body is a great enhancement to just shouldering, and it's something players can learn and appreciate given time.

This is what I personally know about it: No diffuse means "skip the diffuse path code for this light" essentially means don't add/mix this light color/texture color info unto the surface, only use it as a simple b&w light. No specular is essentially the same but for specular textures, it skips the specular component/code/calculation and makes the light less heavy by removing the specular effect. About performance impact, for today GPU's, I don't think is as important as it was in 2004, but still, I'm sure it does have a small impact on performance, for the better of course, specially if done for many lights, but will also make them way more unrealistic. Btw lights with both no diffuse and nospecular, were used for the "projected shadows" or lights used to project fake "shadows" unto surfaces, this was used in Doom 3 to simulate basic, shadow mapping, for rotating fans and grid materials that use alpha textures, all because stencil shadows ignore those. Now that TDM has real shadow mapping, IMO such lights are less necessary and I wouldn't recommend their use for such effect. Thou lights with no specular and no normal mapping, are still useful for some effects, like simulating casting colored light from painted glass, like something bellow, and they are faster then normal lights:

@snatcher I understand that when you feel your work doesn't live up to your goals that you don't want it out in the wild advertising your own perceived shortcomings but that leads to a troubling dilemma of authors who are never satisfied with their work offering fleeting access to their in-progress designs then rescinding them or allowing them to be lost. When I was a member of Doom3world forums, I would often see members do interesting experiments and sometimes that work would languish until someone new would examine it and pickup the torch. This seemed like a perfectly viable system until Doom3world was killed by spambots and countless projects and conceptual works were lost. I guess what I am trying to say is that mods don't need to be perfect to be valuable. If they contain some grain of a useable feature they might be adapted by mission authors in custom scenarios. They might offer instructive details that others trying to achieve the same results can examine. It would be great if known compelling works were kept somewhere safe other than via forum attachments and temporary file sharing sites. I suppose we used to collect such things in our internal SVN for safe keeping but even that isn't always viable. If folks would rather not post beta or incomplete mods to TDM's Moddb page, perhaps they would consider creating their own Moddb page or allow them to be added to my page for safe keeping. Please don't look at this as some sort of pressure campaign or anything. I fully understand anyone not willing to put their name next to something they aren't fully happy with. As a general proviso, ( if possible \ permitted ) I just want to prevent the loss of some valuable investigations and formative works. The end of Doom3world was a digital apocalypse similar to the death of photobucket. It is one of my greatest fears that TDM will become a digital memory with only the skeletons of old forum threads at the wayback archive site.

Historically, there were several inefficiences in the way stencil shadows were combined with antialiasing. The first improvement landed in 2.10, and fixed most of the slowdown (not even tracked, I suppose). The second improvement landed in the just released dev16617-10107 (5851), and further reduced bandwidth. Now turning antialiasing on increases stencil bandwidth by constant multiplier. So regardless of scene, the different between antialiasing Off and 2x and between 2x and 4x should be more or less the same. Another improvement is about soft stencil shadows (6076), also landed in dev16617-10107. It can be turned on and off by cvar r_softShadowsMipmaps (turned on by default). Unfortunately, this cvar can improve performance, but sometimes it can worsen it too. It would be great if players could test it in various scenes and various hardware and report their results. Here are the gory details about the new optimization:

Complaint From Players The player must pick up candles before extinguishing them, and then the player must remember to drop the candle. The player must drag a body before shouldering it (picking it up), and the player must remember to frob again to stop dragging the body. The player finds this annoying or easy to make mistakes. For players who ghost, some of them have the goal of returning objects back to their original positions. With the current "pick up, use item, and drop" system, the item might not return easily or at all to its original position. For example, a candlestick might bounce off its holder. (See player quotes at the bottom.) Bug Tracker https://bugs.thedarkmod.com/view.php?id=6316 Problems to Solve How can the "pick up" step be eliminated so that the player can directly use or interact with the item where it is in the game world? How can so much key pressing and mouse clicking be eliminated when the player wants to directly use an item? How can candles be extinguished and lanterns toggled off/on without first picking them up? How can bodies be shouldered without first dragging them? Solution Design Goals Make TDM easier for new players while also improving it for longtime players. Reduce tedious steps for common frob interactions. Make it intuitive so that menu settings are unnecessary. Do not introduce bugs or break the game. Terms frob -- the frob button action happens instantly. hold frob -- the frob button is held for 200ms before the action happens. (This can be changed via cvar: 200ms by default.) Proposed Solution Note: Some issues have been struckthrough to show changes since the patch has been updated. Change how frobbing works for bodies, candles, and lanterns. For bodies: Frob to shoulder (pick up) a body. Second frob to drop shouldered body, while allowing frob on doors, switches, etc. Hold frob (key down) to start drag, continue to hold frob (key down) to drag body, and then release frob (key up) to stop dragging body. Also, a body can be dragged immediately by holding frob and moving the mouse. For candles/lanterns: Frob to extinguish candles and toggle off/on lanterns. Hold frob to pick it up, and then frob again to drop. Frob to pick it up, and then frob again to drop. Hold frob to extinguish candles and toggle off/on lanterns. For food: Frob to pick it up, and then frob again to drop. Hold frob to eat food. For other items: No change. New cvar "tdm_frobhold_delay", default:"200" The frob hold delay (in ms) before drag or extinguish. Set to 0 for TDM v2.11 (and prior) behavior. Solution Benefits Bodies: New players will have less to learn to get started moving knocked out guards. With TDM v2.11 and earlier, some players have played several missions before realizing that they could shoulder a body instead of dragging it long distances. Frob to shoulder body matches Thief, so longtime Thief players will find it familiar. Second frob drops a shouldered body. Players still have the ability to both shoulder and drag bodies. Compatible with the new auto-search bodies feature. Dragging feels more natural -- just grab, hold, and drop with a single button press. There is no longer the need to press the button twice. Also, it's no longer possible to walk away from a body while unintentionally dragging it. Set "tdm_frobhold_delay" cvar to delay of 0 to restore TDM v2.11 (and prior) behavior. Candles: New players will have less to learn to get started extinguishing candles. With TDM v2.11 and earlier, some players didn't know they could extinguish candles by picking them up and using them. Instead, they resorted to throwing them to extinguish them or hiding them. Hold frob to extinguish a candle feels like "pinching" it out. Once a candle is picked up, players still have the ability to manipulate and use them the same way they are used to in TDM v2.11 and earlier. For players who ghost and have the goal of putting objects back to their original positions, they'll have an easier time and not have to deal with candles popping off their holders when trying to place them back carefully. Set "tdm_frobhold_delay" cvar to delay of 0 to restore TDM v2.11 (and prior) behavior. Solution Issues Bodies: Frob does not drop a shouldered body, so that might be unexpected for new players. This is also different than Thief where a second frob will drop a body. "Use Inv. Item" or "Drop Inv. Item" drops the body. This is the same as TDM v2.11 and earlier. This is the price to pay for being able to frob (open/close) doors while shouldering a body. Patch was updated to drop body on second frob, while allowing frob on doors, switches, etc. Candles: Picking up a candle or lantern requires a slight delay, because the player must hold the frob button. The player might unintentionally extinguish a candle while moving it if they hold down frob. The player will need to learn that holding frob will extinguish the candle. The player can change the delay period via the "tdm_frobhold_delay" cvar. Also, when the cvar is set to a delay of 0, the behavior matches TDM v2.11 and earlier, meaning the player would have to first "Frob/Interact" to pick up the candle and then press "Use Inv. Item" to extinguish it. Some players might unintentionally extinguish a candle when they are trying to move it or pick it up. They need to make sure to hold frob to initiate moving the candle. When a candle is unlit, it will highlight but do nothing on frob. That might confuse players. However, the player will likely learn after extinguishing several candles that an unlit candle still highlights. It makes sense that an already-extinguished candle cannot be extinguished on frob. The official "Training Mission" might need to have its instructions updated to correctly guide the player through candle manipulation training. Updating the training mission to include the hold frob to extinguish would probably be helpful. Similar Solutions In Fallout 4, frob uses an item and long-press frob picks it up. Goldwell's mission, "Accountant 2: New In Town", has candles that extinguish on frob without the need of picking them up first. Snatcher's TDM Modpack includes a "Blow / Ignite" item that allows the player to blow out candles Wesp5's Unofficial Patch provides a way to directly extinguish movable candles by frobbing. Demonstration Videos Note: The last two videos don't quite demonstrate the latest patch anymore. But the gist is the same. This feature proposal is best experienced in game, but some demonstration videos are better than nothing. The following videos show either a clear improvement or that the player is not slowed down with the change in controls. For example, "long-press" sounds long, but it really isn't. Video: Body Shouldering and Dragging The purpose of this video is to show that frob to shoulder a body is fast and long-press frob to drag a body is fast enough and accurate. Video: Long-Press Frob to Pick Up Candle The purpose of this video is to show how the long-press frob to pick up a candle isn't really much slower than regular frob. Video: Frob to Extinguish The purpose of this video -- if a bit contrived -- is to show the efficiency and precision of this proposed feature. The task in the video was for the player to as quickly and accurately as possible extinguish candles and put them back in their original positions. On the left, TDM v2.11 is shown. The player has to highlight each candle, press "Frob/Interact" to pick up, press "Use Inv. Item" to extinguish, make sure the candle is back in place, and finally press "Frob/Interact" to drop the candle. The result shows mistakes and candles getting misplaced. On the right, the proposed feature is shown. The player frobs to extinguish the candles. The result shows no mistakes and candles are kept in their original positions. Special Thanks @Wellingtoncrab was instrumental in improving this feature during its early stages. We had many discussions covering varying scenarios, pros, and cons, and how it would affect the gameplay and player experience. Originally, I had a completely different solution that added a special "use modifier" keybinding. He suggested the frob to use and long-press frob to pick up mechanics. I coded it up, gave it a try, and found it to be too good. Without his feedback and patience, this feature wouldn't be as good as it is. Thank you, @Wellingtoncrab! And, of note, @Wellingtoncrab hasn't been able to try it in game yet, because I'm using Linux and can't compile a Windows build for him. So, if this feature isn't good, that's my fault. Code Patch I'll post the code patch in another post below this one so that folks who compile TDM themselves can give this proposal a try in game. And, if you do, I look forward to your feedback!

Congrats on the release! Remember to check ThiefGuild as well as the DarkFate forums (via Google Translate) for additional feedback.

Sorry - my response was a long way of saying I'd be fine with going to maps only as a strategy. I voted option 1. But this is without understanding some things in your top post. What is an 'Alpha-tested shadow occluder' and how does it affect me as a mapper? What is an example of a translucent object that won't cast shadows?

I thought I've read somewhere that if you enable shadow maps, that on some lights, stencil shadows are still forced, for some reason. Correct? I'm not sure if I should vote. This seems more for fm-bakers. Edit: I would go for option 1

Just curious, based on this discussion: http://forums.thedarkmod.com/topic/19239-soft-r-gamma/?p=427350

Are you saying using (only) shadow maps in missions with a lot of VL gives better performance than using (both) stencil shadows in combination with shadow maps in those scenes?

I think the short answer is "it is possible... but" with the "but" meaning that we have some serious performance challenges. The first RBDoom3BFG release that supported Shadow Maps only applied them to transparent surfaces ( which stencil cannot do ) but the use of both systems in the same scene carried a heavy toll. As I recall, hybrid stencil mode was eventually dropped there too. Still, stencil can look so much cleaner than shadow maps for large volumes and large casters it's a shame to lose them. And hybrid stencil \ maps rendering is still much cheaper than ray-traced shadows or penumbra wedges so it might be worth it to expand the hybrid mode anyway as a sorta "ultra quality" mode.

I know you didn't asked for non TDM mappers opinion but man this decision makes me really sad, imo after so many years, with both shadow systems and still deciding to hard limit shadow maps, to only stencil can do, is like cutting the wings of a bird. Has a player, I can't wait for the day you guys finally decide to remove stencil shadows from this engine. EDIT: Ups I didn't saw the poll at first so my comment was a tad precipitated sorry about that.

The modules are comprised of models, they are completely ignored by the area-portal graph. And now they don't cast shadows if it is proved that light beams travelling though visportals don't touch them. If you use caulk to create areas, then there is nothing that would cast shadows: brushes don't cast shadows because they don't exist (caulk), and modules don't cast shadows because according to area-portal graph they are not hit by light to begin with. There is internal material called "shadowcaulk". As far as I understand, it is not drawn as ordinary surfaces, but it does cast shadows. I think in order to work properly with new optimization, shadowcaulk should be preferred to caulk for the brushes.

Ever since I worked on "Chalice of Kings" with Bikerdude, I have wanted to get flame particles with new particle glares into the core mod. My reasoning was that the candles have glares and the un-glared torches look mismatched. This proposal was met with mixed reactions, so (knowing the history of TDM feature proposals...) I have created a technical demo. You may download it here: zzz_flameglare.pk4.txt (fixed) Just rename without the .txt extension at the end and place it in your Darkmod directory. Here are some screens. Using particles for this is probably the wrong way to go now that Duzenko has an emissive light feature in his branch: http://forums.thedarkmod.com/topic/19659-feature-request-emissive-materialsvolumetric-lights/

Shadowhide has released his TDM FM and it needs a release thread here. I'll quote from his release thread on TTLG. Edit: Shadowhide has released v.1.01 now which is compliant with TDM2.0 & a few other changes (like the music and loading screen). Here's the new download: http://rghost.net/48078929 http://darkfate.org/...ceptive_shadows

@stgatilov In Written in Stone at 308 -1768 123 -13.7 68.3 0 (noclip) using stencil shadows (r10166), the FPS drops from 60 to 45-50. There is no FPS drop with r9853/2.10; it's 60 fps. I found that enabling Frontend Acceleration improved the situation and FPS was a steady 60 fps. Summarized: Frontend Acceleration enabled r10166 stencil 60 fps Frontend Acceleration disabled r10166 stencil 45-50 fps r10166 maps 60 fps r9853 stencil 60 fps I thought you might want to investigate this scene. Maybe there's an optimization that can be done.
