@danmoreno i tried it out, it works okay. to make life painful i did it in one dop and using sparse. i recommend 2 dops for simplicity

find_densitymask on the left looks for the intersection of the rising smoke and the sphere and handles the dissipation inside the sphere. transfer_density on the right side reaches into the other dop object and uses the densitymask as an emission source. because it has collisions on, the smoke stays inside.

warning: this one-dop-sparse setup has all sorts of dumb shit to keep the second solver active and tracking the other one

in the textport you can do `vexprofile start`, play a few frames, then just `vexprofile` and you get stuff like “`/ -> vexprofile start / -> vexprofile —————————————————————————— VEX profile listing generated: Sun Mar 8 12:40:51 2020

idk if there’s a way to have it list your own functions in there though – does xnoise only appear because it’s actually a native vex function and not something defined in a header?

Yep Fusion relies on Viewers – here is fusion comp on how I go about it getting ACES to work when rendering from Houdini / RS if that helps.

I also set up my OCIO variable in my env system so you do not have load it all the time at least in FUsion which is annoying – Also it keep consistency through out the different DCCs.

this should work with all apps that can read OCIO – Houdini/ Maya / Fusion / Nuke – etc

If you see anything wrong – let me know 🍻
