I have an animated open model being converted to a density VDB using VDB from Polygons. Each voxel only store a 1 if it contains geometry, 0 if it does not, which means that polygon surfaces that get too close to each other or interpenetrate each other don't get sampled twice. In these cases I get a loss of total density in my VDB and a “pop” in my render where it happened. Anybody knows of a fix or workaround for this, so that two polygon surfaces in the same voxel actually increase its density value?
