I got it. We need a normalized lightness texture. Smile

Lab colorspace Lightness channel + normalize:

@MirceaKitsune
Do you mind to update the color textures. Extract lightness channel. Normalize it. Store as lightness.png.

- NaN - 05-09-2010

Looking at the normalized lightness texture right now. What we need is actually an ambient occlusion texture.

edit:
The rendering would go like:
1. Alpha blend color with skin.
2. Multiply by ambient occlusion.

- NaN - 05-09-2010

Any volunteers to bake ambient occlusion textures for our cars?

@joe
How fit are you in fixed function OpenGL? Alpha + multiply blend should be possible without shaders too I think.

Here is a tutorial how to bake AO in Blender:

Edit:
The AO map for the 360 took me like 5 minutes. Import body.joe+body00.png. Assign a material. AO with 10 samples.

Yeah. I just converted the current skins to a grayscale png and renamed them to color.png, then made a copy of it the body01 with the parts that musn't be colored. Hope it is ok and working now.

I checked in the color selection gui (rev 2708). It is non functional for the moment. Comments are welcomed.

I've got the skins ready (needed some fixes here and there).

Should I overwrite the current body textures with the new ones or give them another name, body-00.png instead of body00.png?

I would tend to overwrite the existing ones and point last release users to the previous vdrift-data revision and update cars.vdrift.net accordingly.

- joevenzon - 05-27-2010

I agree.

- NaN - 05-28-2010

The new skins are in trunk(r554).

There are still a number of cars using old skins, need some more work to get them ready for coloring: G4, M3, M3D, NS, TC, XM, Z06. Volunteers are welcomed.
