Hello!

I've been trying out vertex animation in unreal. Everything appears to be fine except that the normals have sharp edges at times and flicker when in motion. I hope this isn't an issue with lower-poly vertex animations cause we have to keep the export at or below 1k prims. I also tried soften normals and it didn't appear to help in unreal.

I'm using Houdini 18.0.348 and Unreal 4.25.

Thank y'all for any help!

I have the same issue, but with the character. Normals are jittering.

Bump!
I'm also having the EXACT same issue. Has anyone else had issue with this?

I still haven't figured out how to get them to completely stop flickering.

It seems it's a lot to do with the lower amount of tris I was aiming for. So allowing it some more tris, turning off equalize edges and using a polyreduce to get it to as close as the end tri count as possible before the Labs Vertex Anim Textures helped. Not perfect though.
