Hi, I am looking for auto-activation for source volume node in DOP based on an input object(VDB, houdiniSDF). This is because sim is broken, if the sourceVolume set to collision and there is no SDF primitive(@name=density or surface).
So far, I tried 2 methods, but not working.
A - use expression in activation, but something not right.
B - use enableSolver, but probably it needs to place inside of the sourceVolume.
If anyone has better ideas, please let me know, thanks
