Hi,

I can dive into "Particle Fluid Surface" and find it uses "VDB from Particle Fluid". There is a parameter in both of them, called "Particle Separation". I would like to set this parameter for each point differently according to the point's attributes(and probably also the surrounding density). Is it possible for me to know the implementation details of "VDB from Particle Fluid" and what "Particle Separation" is doing? And can I extend this node in Houdini or is there any open-source alternative?

Thanks,
Roden
