Vellum and Pyro - Two way Interaction

Recommended Posts

Pavel, the smoke is actually colliding with something on my setup. Do you know what is it? Is it just the vellum points?

It looks like it, but it is not - if you simulate only the smoke, you will see the exact same behavior. I guess it is some kind of computational error or just the pressure solve doing its own thing.

Edit : it is an error caused by the advection method.

Coool, thank you!
Just one more question.
About the SOP merge Field nodes. We did you multiplied the Source Pre-Mult by -1 on the collision but not on the collision vel?

Yeah, thats because vdbs and houdini native volumes are using reversed sdfs. Velocities are just fine.
