Reverse time sim

Have an urgent question. Couldn’t find answers on threads. Can you reverse a captured simulation .bob, if you need for instance, an Ivy sim to retract into its origin? That is, using time node? I tried to capture alembic but bifrost crashes with the instances to mesh being too heavy a load. So this is specific to whether one can do this with .Bob files.

The time node will output the frame number. Assuming that you are using the frame number from the time node to load in the correct .bob file, one simple solution is to play the Maya timeline in reverse. If you don't want to do that, you can do some simple arithmetic on the frame number before piping it to read_Bifrost_object, i.e. computing max_frame - frame (for example, 120 - frame).
