Hi everyone! I'm very new to SpeedTree, but I thought I'd learn it for a personal project I'm working on in UE4. The title speaks for itself. When trying to export to UE4, I can't see any clear way to get the essential packed texture with AO, roughness and metallic information. I only get the color map, normal map, and a subsurface map. I can't find any information about it online either, and all tutorials I've found on it appear to be happy with color map and normal map and don't bother with anything else. Really? I also find it annoying how SpeedTree is using gloss instead of roughness, so I have to invert the map and hope it looks correct in the export.
How am I supposed to export the additional texture maps when exporting?
