Hi,
I am facing one bug in UE4, and currently using version 4.5. The bug is as follows :
When I am using unwrap UVW modifier and flattening the mapping and then import in UE4, it works fine. But , for example in the below picture , after flattening the mapping also , I am unable to get proper tiling.
So I need to apply another UVW map modifier with Face Mapping , as shown in the below picture.
This is what I want. But when I export this and the import in UE4, it shows indefinite progress bar for several minutes before showing the crash report , as given below :
