Hi there, I'm a beginner using Houdini and am new to the community.

I followed the tutorial on how to make smoke (https://www.youtube.com/watch?time_continue=457&v=r_WErTEvAic) and followed the steps, step by step, yet my smoke doesn't seem to rise - It seems to stay in one place, looking like a ball of smoke. Any ideas on what I've done wrong?

Thanks a lot

Mario.

I’ve not looked at your file but the default buoyancy value on the solver changed a few versions ago. Try increasing the buoyancy value, also make sure that your smoke has a default temperature of 1 or greater - that’s set in the smoke source network, not the sop network.
