Last night we chatted on Discord about Vulkan support and PBR, bringing up a system for adding proper reflections once more. I suggested screenspace reflections but it was argued reflection probes would still be better than SSR in our case, a ticket for that is already open but I'm uncertain whether it's the best way: A manual approach would need new entities to be placed by the mapper... this requires extra effort and would exclude old FM's that are no longer updated, while the result will also be inaccurate and static meaning you won't see an AI reflected as they walk on a shiny metal plate for instance. If PBR with realistic graphics can be a hope for 2.12 or later, we'll definitely want to do it right rather than using a limited / limiting system. A technique came to mind that might just work for our engine and setup. I wanted to share it here before I forget the specifics; This might already be a common practice and even have a definition, for the purpose of this thread I'll just describe it as I originally imagined it and feel this would work for our engine. The idea is we'd use reflection probes but in an automated fashion: A probe is automatically spawned in every valid area (within bounds) in the player's view, at a given grid unit size. For example: If the grid scale is 16, a probe may exist at position '0 -48 16' another at ''0 -48 32' and so on. Every point projects its result on all surfaces in its radius which contain a specular channel masking it, the best alternative presently available till we were to convert all textures for PBR support. The cool thing is the same cubemap can also be projected as a light source, allow for global illumination in addition to just reflections! This would be similar to how the Irradiance Volume works in Blender / Eevee except each dot renders a little cubemap from its perspective. I already know what everyone is rightfully thinking: This is going to kill performance! After all each probe needs to produce a render from its perspective, and being a 360* panorama it will open portals in all directions. Normally that would be insane, but I thought of various ways in which the impact could be greatly minimized to very bearable amounts. The frame buffer of each probe will be at a very small resolution by default since much detail shouldn't be needed. Even 64x64 per cube face might do. Each probe only needs a draw distance double its grid size, given it only has to see as much as is necessary to fill the gaps between it and its neighbors. So if the grid size is set to 64, each probe would only have a draw distance of 128 to cover the space in between its neighbors, nothing beyond that would exist to it. Only probes the player can see would ever be spawned and calculated; If the view frustum doesn't overlap the virtual cube who's corners touch that probe's neighbors, the probe is dropped from memory. Probes are also only spawned in a valid visible space, never out of bounds including rooms culled by portals. A draw distance after which probes are removed or not spawned can also be included. This would further help by making any probe further than X distance be ignored, slowly fading away as to not noticeably pop in and out of existence. Reflections / GI are a discrete effect you'll only see up close. Similar to lights and shadows, the result of a probe should be cached and not calculated unless necessary. This means that unless something moves within radius of that probe its cubemap won't be rendered again. Probes would only be updated either when they first come into the player's view, or if something touching their cube has moved. Note that particles and lights with animated textures would have to count as you may see them in a detailed reflection, candles and torches would force constant updates per-frame for probes they intersect. If with all that performance is still affected, frame skipping is also a solution: Reflection probes can update at a lower frame rate to further decrease their impact. If you have a 60 Hz monitor and are running TDM at 60 FPS max, reflections could run at 30 / 20 / 10 FPS without looking out of place. They could in fact be defined as a fraction of your average framerate, so for the FPS you get you can decide whether it's going to be 1/2 or 1/4 or so on of that... this would have the added advantage of exponentially gaining back FPS the lower your FPS goes. There are several reasons why I believe this would be better than mappers manually placing new probe entities: Extra work is required for the mapper, who needs to figure out how to cover each area in probe lights. Every piece of the map would need to be encompassed in a reflection / GI probe otherwise you won't get shiny surfaces or bounce lighting which will look out of place. Most existing FM's will never be updated to use this: Only maps created or updated after the feature is introduced would benefit, anyone playing old missions will get boring visuals without reflections / GI which will be inconsistent to new ones. I strongly believe this should be done as an universal effect like SSAO. Single large probes will produce inaccurate results; The larger a cubemap is, the more drift and a fake results you get with distance from its center. This can be mitigated by using parallax corrected cubemaps which should be used for automated cubemaps too... none the less you get a single point of vision for a large room which makes the result inaccurate the further you go... with an automated approach you could have many probes in a dense grid (if your hardware allows it) for a much more accurate result at any position and angle. What are your thoughts on this solution, do you think it's realistic and can work out? I do believe it should be either this or screenspace reflections the way they're done in Godot or Blender / Eevee. If SSR isn't the right choice for our engine, reflections and global illumination alike could be captured using a global grid of capture points shining within their respective areas.

Not so long ago I found what could make a pretty good profile picture and decided to try it out on these new forums. But I couldn't find a button anywhere that would let me change it. I asked on Discord and it seems Spooks also couldn't find anything anywhere. So I logged into an old alternative account and, lo and behold, that account has a button. This is on the first screen I get when I: 1) click on my account name in the top-right of the browser -> 2) click on 'profile'. Compared to my actual account: Are you also missing this button on your account? It'd be very much appreciated if that functionality could be restored to any of the affected accounts.

Hi, I need to know what the code is to use Spoiler Tags. I am using my tablet and I don't have the options to use anything, like spoiler tags, quote tags, text changes etc. Thanks

Hi guys, through the "cheats" topic I got the idea, that it would be quite useful, if there were tags for missions (the post was about removing the killing restriction in some missions to suit the prefered play style). I don't know how easy or difficult this is, but with them, it would be quite convenient to pick missions with playstyles, environment, etc one does want to use. This could also be expanded to other mission properties. I remember a discussion about climbable drains, handles on doors, that cannot be picked and other things the map author chooses for himself. That way these things would be clearer and as I said before, it is easier to choose missions with playstyles that suit oneself. What do think?

Hey, Every time I've try to use the Full Editor when PM'ing someone, and every single time I get an error. Whoever is in charge of the forum, is it possible that this could be fixed? Thanks Neon
