Volume collision voxels visible in rendering

Recommended Posts

Posted (edited)

Hi everyone,

did a pyro sim along with a collision object. When I up the density from 1 to 4 in the pyro shader, the voxels are getting visible (attached an image to the post showing the issue). Is there any way to prevent that or soften the voxels on the outside in a post process or something?

Cheers,
Christian

You could try a VDB Smooth perhaps, but your best bet it to boost density prior to simulation rather than afterwards in the render.

Thanks @Atom. Unfortunately too much detail is getting lost when using VDB smooth. However, decreasing the volume step rate in mantra (to 0.2 and below) seems appropriate and gives finer control to blur the voxels visually without loosing too much detail.
