Hi all, I am a beginner on Houdini and I am currently having a problem with the VDB. On my rendering I have a lot of small pixels, and on my viewer I have a kind of blur, I tried to increase the “division size” (0.05) but it did not change anything. I will need your advice! thank you !

Increase the stochastic samples to around 10-12 samples from the default 4 (if I'm not mistaken).

You can read more about reducing noise in Volumes from the docs. http://www.sidefx.com/docs/houdini/render/volumes.html [www.sidefx.com]

Remember that the volume visualization in the viewport are often not the final representative when you render it in Mantra as it depends on the Pyro shader setup.

I'd also recommend turning off preview render (see attached) to test noise using buckets instead.
