Hi,

A simple question but I can't seem to get the answer.

I need to convert a sphere primitive to a volume, when I do this with a VDBfromPoly instead of the VDB showing up as a perfect sphere I get this low res sphere similar to what you would get with a low frequency poly sphere (see screenshot)

Is there something to tweak to get a perfect sphere, or is there a better way to to convert from a primitive straight to a volume?

P.S. The reason I need to do this is because Im copying a few hundred thousand spheres to points and if I try to do this with poly spheres houdini crashes always.. only way I seem to be able to do it is by keeping the original sphere a primitive.

Thanks!

Instead of using spheres, you could just replace each sphere with a point at it's centre and assign it a pscale attribute which is the radius of the sphere. Then you can use vdbfromparticles and get a perfect sphere for each one.

If you want to use actual geometry have you tried using polygons but on the copy node turning on pack and instance.

Thanks guys you are geniuses. Tony I already had the points with the pscale on them thats where I was copying the sphere to! Did not know I could go straight to VDB from particles, neat one!

Evan that one slipped by, would have saved a lot of headaches. Thanks for the help!
