I exported a simple rbd simulation from houdini to UE4,everything is work except the diplay(In Unity,it's display right).Is that because normal or hard edge?
In houdini




In UE4

Hi, that probably has to do with your normals. What shading mode are you using inside Houdini? Try setting it to smooth shaded, which should give you a more accurate preview.

To fix your issue in Unreal, make sure you have correct Vertex normals in Houdini before exporting. (create these before your geometry goes into your simulation)

The shading model in that picture is flat shaded

This is display in Houdini.N is on vertex now ,How can I fix this normal?
