Boolean from Blender
Boolean modifiers applied in Blender 2.8 do not fully cross over to AD. I made a watch with holes in the arm band and AD only recognized 1 hole. On the other item with a boolean modifier it was just a shadow. Opened the obj and fbx versions in windows 3d viewer and the model looked just fine. Frustrating because I spent money on 3d materials and everything from Adobe for the program not to want to recognize modifiers.

same problem with cinema 4D and Cheetah3d here. AD seems to have a problem with objects who are manipulated with boolean operators
