Hello,
I'm using a filecache to save a popnet simulation, how can I read it inverted to obtain like "a backward effect" of my sim??
Of course I already tried with a negative increment, but it didn't work...
Is it possible directly into the filecache or not? Maybe with a Timeshift after the Filecache?
Thanks in advance for your answers!
How can I reverse a Filecache reading?

OK it works if I just reverse the Output Frame Range, Houdini understand itself the negative step! Cool!
But... When I play backward the sim, I lose the orient of the point for the last frame, and for an appearance effect it's a mess into the pieces of my object... :/
I'm not sure where you're seeing an output frame range, is that with the retime node?
With the timeshift node there is only a frame or time parameter, so to reverse the playback, remap the frame value to the reversed range. For example, put $FEND-$F+$FSTART for the frame expression, or link to the file caches start and end parameters instead of using the global variables.

Ok I understand well your tip, and it's noted! Thanks for the idea!
In my case, I just inverted the "Output frame range" in "Fit range" mode and Houdini understood to use a negative step (look the screenshot just below), cool!
Again, thank you so much, you saved my day!!
