VDB Artifacts when converting back to polys

Recommended Posts

I am working with VDBs for collisions ... everything looks good up until the point that i convertvdb back to polys. I am getting visible voxel bands in my mesh.

Can someone tell me how to avoid this ? VDB on top ... Conversion on bottom.

There's no built-in tool to regain the topology of your initial polys. Is there a reason why you're doing the round-trip?

Maybe you should try to reproject your output mesh (that came from VDB) onto the initial one (before being converted to VDB) ? If the geo are close enough, using an attribute transfer and transferring P could work...

Hope that helps
