I have encountered a problem. I created a particle sim that is using VDB for collision. However when the VDB collision hits the ground where the particles are located, they start to glitch out.
At frist it though it may have been a viewport error. I rendered a quick test out to see it it was, sadly it was not.
I have attached videos to show what is happening, anyone have a clue how to fix this?
Because of particles trapped between your proxy volume and ground, they start to jitter! displacing your proxy volume a little bit higher will solve your problem. See attached HIP file.
