The MoreAdvancedVehicles project (using JME 3.3.2-stable) issues a warning while loading the tank asset:
Jan 24, 2021 4:53:23 PM com.jme3.material.Material checkTextureParamColorSpace
WARNING: The texture Models/Tank/Tank_Occ_Rough_Metal.png has linear color space, but the material parameter LightMap specifies no color space requirement, this may lead to unexpected behavior.
Check if the image was not set to another material parameter with a linear color space, or that you did not set the ColorSpace to Linear using texture.getImage.setColorSpace().
Does anyone know a way to avoid this warning, short of configuring Material.logger?
An identical warning occurs in the TestPbrLighting app of jme3-examples, which is simpler and thus easier to debug.
I do not, but I would love to know the answer as I get that warning regularly as well. At one point I had investigated it and found that the texture was flagged as linear from the material, but for some reason I still get the warning.
That was just the code I was using for getting the textures from the material when I was looking into the warning several months ago. The code does not have anything to do with loading the textures or the color space, as by the time I extract the textures from the material the texture is already loaded and the warning has already occurred. It was just a convenient because it already pulled the textures from the material. I’m simply showing that the texture object I checked was pulled from the material.
