I sim a foutain water in houdini flip,and I want to export it as a loop animate 1~100frame.But I cant find anyway to loop the flip cache,the particles or vdb?

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

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
