Hey everyone,

Has any of you encountered this bug in Houdini 20 while using the flipsolver?
Basically I'm doing a simple small scale fluid sim and when I dive in to add a popforce (or anything else) and then go back, it displays all the collision geos and they just don't go away, even if I dive back in the Object level they are still visible in the viewport. Even if display collisions on the solver is turned off. This is really frustrating. I can't share screenshots unfortunately.

It's a known issue with Houdini. I think H20 is better, but there are viewport bugs holding onto "stale" data which produce the anomaly. It's not just FLIP related, other simulation systems using visualizer can cause the problem as well. Click the X to destroy that copy of the viewport and use the + icon to add another. That typically fixes it for me. Otherwise, you have to restart Houdini.

I'll try that, thanks a lot!
