SDF Collision with smokesolver

[mosssi]

Hi guys,

I'm doing a dust simulation using smokesolver. I used a VDB from polygon sop and created a SDF version of my deforming, collapsing building for collision object (volume sample). The problem is the SDF collision just clears the smoke when they are colliding and doesn't change the flow at all. I tried to create a sample hip but it seems correct with a simple box. Did anyone have the same experience before?

and I should mention that my SDF resolution is enough and.

Thanks for noticing

Did you transfer @v into another vdb, and name it correctly? 

I have some notes here:

Thank you matt

No, I didn't. I just used the SDF as static object . I didn't know that I should use it as a source volume. I'm trying this now and I will post the result.

By the way you have a really great wiki. I will come back to it later.

Yes, I don't know why I skipped this video before. It has some new information for me.
