MaterialProperty color override incorrect results

Unity Engine

Two cubes with the same unlit material, right one with a material property override with the same color values. At runtime the overridden one is lighter.

The material property overrides are unable to do automatic sRGB conversion for colors. Unfortunately, currently if you want the color to match, I think you have to store the color values in linear space to the IComponentData.

I think in your case, using material property values of (0.163, 0.296, 0.787), which is the linear space equivalent of the sRGB color (0.44, 0.58, 0.9) should hopefully produce a matching result.

You can convert between the two using the Unity APIs Color.linear and Color.gamma.

Thanks for the explanation :slight_smile: Those APIs will be put to good use ^^

Thanks, I’ve also encountered the exact same issue ( and thought I was going insane ). I’ll try out the linear conversion.
