Hello,

I'm trying to import vertex animated destruction inside the UE4, but I always get stuck on mesh import. I export it from Houdini, including textures and material code but when I try to import I get “all of the polygons are degenerate” error message and then it just fails (see attached).

Does anyone know how to fix this?

I tried polydoctor, fusing and numerous other ways of fixing the geo - doesn't seem to work.

Quick update: managed to get it working with SOFT option in exporter. I believe that's not the correct way of doing it and you need to use rigid body export instead (the one that doesn't work).

Please don't bump your posts….thanks.

i had a similar problem at exporting fbx with the “GameDev_lodCreate” sop. i had holes of degenerated meshes on import in ue4.
i simply scaled it to 100% before the lod-sop, this fixed this problem.
i also had an error at import in ue4 “could not triangulate mesh”, this was because by default in the “GameDev_lodCreate” in “Advanced” there is “remove inside faces” checked, after unchcking i didn´t get the error anymore. i was exporting shells maybe thats why that was a problem.
