Just one question because I don’t know if it is a bug or I’m missing something. I have a FBX with several meshes inside exported from 3DSmax. I try to import the FBX as Combine in Unreal and it doesn’t make anything, Unreal keeps thinking long time and I have to kill the application after one day trying to import the FBX. I don’t know why this happening from Unreal 4.17 and it also happens in Unreal 4.18.3. I’ve made the same setup with Unreal 4.14 or 4.15 before and I didn’t have this problem. If the FBX is not combined Unreal imports all meshes without any problem after a couple of minutes.
