VDB mesh + Point Deform precision


Recommended Posts

Hi guys!

I'm doing some tests with VDB and Point Deform SOP to recover original geometry point animation. The thing is I noticed when the VDB mesh result have a slightly different shape, the point deform SOP lose precision to move the new points. Is there any way to improve this? You can see what I'm talking in this basic example:

If I raise the capture radius from 0.1 to 0.25 it works like 90% but only with this basic example, with a more complex element, my working scene, have some weird results displacing some parts of the geometry, and this happen if I change the capture radius or maximum points too. Maybe because I'm generating the hair / tentacles border with VDB dilate and the original geometry doesn't have those polygons?

Is there a better technique to achieve this? I'm trying to use the VDB mesh because I want to generate motion vectors and rest attribute for procedural shading. I uploaded the basic scene if anyone can take a look.

Thanks a lot!
