Being a game developer, I was thrilled when full PBR support was announced for Blender many months ago. The other day I finally tried to bake and export a set of PBR textures for use in Unity, and with great confusion I noticed this:
I can’t tell if this is a bug or a careless mistake, but there doesn’t seem to be an option for metallic baking here. Surely this isn’t hard to fix. The necessary data should be all there. I just want to direct your attention to this in case you’re not already aware of it. Please, complete Blender’s basic PBR-related features soon. Thank you!
