Yes, let’s move to another thread, since this looks specific to Reality Composer 
Thanks!
I’ll try to repro in the meantime. The NormalMapTextureChecker warning looks weird. The NormalMap image itself is technically sRGB as it is a PNG, so I don’t know why it is trying to enforce that it be raw? It should be converted to raw in their shader, internally… maybe they don’t do that and want us to do it for them?
