2025.32280 - POP Attributes Oversized

Hello Derivative team,

I’m not sure if this is a bug, but while developing a plugin, I noticed an issue: Starting from a Torus POP and feeding its input attributes into a Proximity POP while dynamically changing the maximum distance, my plugin threw this error: “Attribute buffer ‘Tex’ is not large enough for the number of required vertex elements.”

Upon inspecting the attributes generated by the Proximity POP, I saw flickering in the vertex tex attributes. Saving the patch under a new name produced a different result, with excess values in that attribute zeroed out or changed. However, replacing the Proximity POP with a fresh one brought the flickering right back.

This was tested in Mac M3 Max Tahoe 26.3:
Attribute Oversized.toe (5.9 KB)

Hello @Alaghast

The Proximity POP keeps references to the input vertex and primitive attribute buffers when it shouldn’t. This will be fixed in the next release. Thank you for reporting the problem!

Thank you!
I confirm that i don’t see it anymore from 2025.32460
