Volume IsoSurface Rendering Issue with Surface Attributes


Recommended Posts

Hi all,
I'm trying to look into using isosurface rendering of VDBs rather than take the extra step to convert them into polygons. In doing so I have ran into an odd problem. Whenever I use a VDB From Polygons node and add a surface attribute to it, the isosurface render fails.

I have attached a hip file to show this. With the vdb_from_polys_normal output flag set you can see the render is normal. If you then activate the display flag on the with_surface_attribute node, the render will show nothing at all.

Is this normal? Admittedly I cannot find out how to use the volume surface attributes, but I'm thinking it should still render. Maybe a bug?

Note: in the shopnet1>iso I enabled the isosurface rendering by adding the vm_volumeiso and vm_volumedensity properties.
