So, what are you working on right now?

4) If you want interior cubemap ambient lighting, use envshot to capture an in-game cubemap of the location then perform steps 2 and 3 on the envshot images.

What location are you suposed to use for the envshot? Just the middle of the room?

Should be where you intend the light center to be. Doesn't need to be precise since the images are blurred

The simple "TLDR" version:

1) Obtain or create a skybox cubemap

https://wiki.thedarkmod.com/index.php?title=Category:Skybox

2) Use a 3rd party tool to convert it to an irradiance cubemap

3) Create a material def that uses the irradiance cubemap

https://wiki.thedarkmod.com/index.php?title=Light_Properties#lightAmbientDiffuse_and_lightAmbientSpecular_(_Previously_ambientCubicLight_)

4) If you want interior cubemap ambient lighting, use envshot to capture an in-game cubemap of the location then perform steps 2 and 3 on the envshot images.

I always appreciate your effort nbohr.

This is a topic about using the ambient cubemap:

I think the instinct to suggest ambient cubemap lighting is because your church has unreadable geometry due to the flat ambient lighting and same texture all over it.

Other than ambient cubemaps, you can ( in order of least to most difficult

1) Enable SSAO and increase your SSAO radius ( r_ssao_radius 128 , etc)

2) Place dim lights around the church to emphasize contours ( this is typically called "bounce lights" and you use the ai_see 0 entity arg to prevent the light from impacting the lightgem )

3) Simulate AO via grime decals

4) Re-texture parts of the church with textures that are similar but have different shades to simulate some directional lighting

5) Export the church to Blender and bake lighting to a texture in Blender then export the baked lighting as a model with a blend filter decal material to overlay the church

6) Use the "Strombine" lighting technique:

I forgot to add easiest option 0 to my list: Tell players to use the Fresnel mod

https://www.moddb.com/mods/the-dark-mod/addons/fresnel-mod-212

I usually pair with SSAO anyway so I guess it counts as option 1b.

That does look nice. Surprisingly, this is the only mod I have tried yet in TDM. By SSAO, do you mean the Ambient Occlusion option in the game menu, or is this another mod?

 

[nbohr1more]

The in-game Ambient Occlusion 

[grodenglaive]

well that was a huge PITA, but it seemed to work. 

Here's the before and after with the custom ambient cubemap in the second pic instead of ambient_world. The church is a bit too bright, so I'll need to play with it, but at least now the shading isn't so flat.  

(edit) note that ambientCube will also appear on the interiors.

Here's another angle. Now the bumpmap is actually bumpy!

Oh, and I used cmftStudio to convert the cubemap skybox into the irradiance cube.

Now that I know the whole process, it isn't that bad, but I don't think I would bother with it for the interiors.

I always thought fresnel mod was about giving objects a sensitive glow instead of doing a cube map magic?

You can use a fresnel effect to highlight edges but it is also a real world effect that causes specular reflection intensity to increase at grazing angles. That effect would make the flat looking church geometry look more volumtric and easier to read.

Ah okay thank you. So your post was more about the church and not the cube map topic. Ah, I gotta read much more about these topics. But again thank you for taking the time to answer my still So foolish questions after all these years

[Frost_Salamander]

anyone fancy a drink?

[datiswous]

Ah so you could order a drink from the section above? Would be nice if it would include a dumbwaiter.

Still working on the comfyUI "workflow". As all was looking very good at first glance, there were some things that didn't work as they should; mainly producing decent seamless tiling height (depth) maps. But I got that figuered out with a trick:
Make a 3x3 grid with the diffuse (color) map (scaled to 512 so the combined image is 1536)  > make a heightmap of that and crop to the center, so the output is 512 again. And it works (using geowizard nodes that produce a height and normalmap).
Added bonus: The seamless tiling normalmap from geowizerd can be converted to a height map with deepbump, that produces seamless heightmaps also, but in a very different way: they can be blended together to get a very decent result.
Added bonus 2: The normal map created from the diffuse map with deepbump was already quite good, but now there is the normalmap created by geowizard also, both tiling seamless: They can be blended together (to have more or less detail).


Also I added a way to reduce the highlights and shadows from generated images a bit; that is still a problem with generating textures with AI. Prompting: "A floor that looks like a stone wall" works a bit but doesn't work with a door somehow.
AI models are trained on images with light coming from above. Althought there are (re)lighting options, they are trained on humans and objects, not on walls and doors and stuff ... so that is still a limitation.


Maybe I should train a lora on perpendicular lighted vs top lighted  surfaces ... : )

Robot spider / scorpion, can be lockpicked. Monocycle robot opening  / closing doors. First one uses modyfied tdm spider, just noticed that they dont have rotation animation, just slide around axis without proper leg movement. Razor rider is a simple script without any tdm ai thinking, with customised navigation points.

Using skull-storm to open doors, neat!

Its a placeholder, I was thinking about rotating buzzsaw-shuriken, as the robot have splitted head just like ... lower part of his body.

That looks amazing! New AI models are something I've been hoping we could see for some time: We can definitely use more steampunk robots, fantasy creatures, and why not some bigger and scarier undead like Doom?! I hope those models can be perfected and included in a future release.

Both of them are far from fitting AI category: monocycle is an animation with extra steps, and spider is using invisible nonsolid ai spider + separate model for every part of leg. every part is operated by script reading ai spider's joint position and angle - and modify it. In this case upper front appendiges are spider's front legs moved far up, pincers use spider's mandibles animation. You can make humanoid ai have backward bending knees, or even reverse its movement so invisible ai is walking on the ground but visible parts are walking on ceiling. Ofcourse it require that ceiling geometry mirrors floor shape, and ai sees and reacts as it is actually on the ground.

I just love a nice, burglar friendly mansion. Cool shots, especially the first one.

Thanks man! Yeah, there will definitely be plenty of ways to get in and out of this place
