UASTC compression on Metallic/Roughness changes the colours

I agree but thats not what I’m seeing from the modelviewer screenshots there, right?

Anyways, will look into it

It is less noticeable on this more recent model as its Metallic texture is very different to the texture at the top of this thread which was becoming too dark when exported

I have another model this happens with I can send for a repro, a GLB file that looks perfect if exported with the GLTF Object Component. If exported with that component removed, the metallic/roughness is significantly different

this looks like specular again, not colorspace

I have a fix locally that I’ll release later today (tbd testing)

You’re right, the specular is changing, comparing the models now, hopefully that fix is it!
