Update Solver with Animated Alembic Geo


Recommended Posts

Hey guys,

I have a solver with a simple infection vex code that spreads the source for a pyro sim across a logo.  The log later breaks apart, and is an imported alembic file.  I can't figure out how to get the solver to update the alembics' animation each frame so that the fire will follow the parts that break off of the logo.  I'm new to Houdini, and did a good amount of research, it looks like I need to tell the Prev_Frame node to look at an import of each frames deformations, I can't figure out how to do that however.  Project attached, any help is appreciated, thanks!
