So um, in short, I ran into a problem, I saved the asset in fbx using Fbx exporter, set everything up correctly (probably) and when I loaded the file into blender, it turned into complete mess and chaos, everything was either changed in size or was turned upside, so do textures.
down and moved incorrectly, so do textures.
In earlier versions there was a workaround for doing this, but I thought that for recent versions it was automatic. I’m not sure what the solution is other than googling the error. Chances are others are experiencing it.
