FIXED:Memory Leak with Animated FBX imported as POPs

Bugs

When I import animated FBX files as POPs, TouchDesigner’s memory usage slowly creeps up until it crashes.The leak rate seems proportional to the frame rate and the complexity of the geometry.

Turning off the Deform POP seems to make it stop but then it’s not very usable.

Importing the same model as SOP doesn’t leak memory.

This was happening in version 2025.33070

Thanks for the report – I’m able to reproduce the issue. We will take a look into it and let you know once we have a fix.

This will be fixed in the next official build we release: 2025.33152+.
