Roughtness, metallic and height textures.
Will supoort of them be implemented to future FSO revisions? I recently converted a model and it looks soo poor compared to IRay render of Substance Painter. I know FS will never look as good as modern renderers, and IRay is actually not desiged for ingame usage. Anyway lack of channels mentioned above give me less control about the model look at all, and it's stripping it completly from it's deep lighting reflection of the surface. Recently released GTF Hydra suffers from this problem too.
