There, I fixed it by removing all clamps from the shaders.
Before:
float3 tempModelColorBase = clamp( modelColorBase.rgb / modelColorMapTex.a, 0.0, 1.0 );
After:
float3 tempModelColorBase = modelColorBase.rgb / modelColorMapTex.a;

I have no idea whether anything breaks after that. The HLSL compiler doesn't infer types right for some reason and thinks that 1.0 is a vec3 value.

Okay, a more correct way is not to remove clamp completely but cast the second and third params to float like this:
float3 tempModelColorBase = clamp( modelColorBase.rgb / modelColorMapTex.a, (float) 0, (float) 1 );

This way it works. Please fix for all shaders in the mod that contain clamp.

I didn't saw your thread till today (I'm not used to workshop stuff but learning) .. I'm very sorry for inconvience and will work hard to fix it. Thank you very much for suggestion.

should be fixed in GunGame 0.25 RC .. please feel free to check it, I have no linux but exact casting to float is used in all shaders where clamp is used. Looks like 1 != 1.0 in bitness for shaders same as most programming languages.

Well, almost a month has passed but today I tried GG with friends and indeed this bug is fixed, everyone is visible. Thanks again!
