Hello, I have encountered a few problems with 3ds max, trying to get my content into the game. Maybe someone with more experience could help me out. The first thing is the 'Top level must be Multi/Sub.' -error message. Sometimes exporting an object works fine, and sometimes it doesnt. This is my material: My second issue is that I cannot get the alpha channel of my texture working. This is the alpha channel in photoshop. I tried quite a lot and I'm stuck here for a few days already. Just let me know, if you need any further screenshots. Would be nice, if someone could help me out.
