Crash when applying Line MAT to a subdivided POP

POPs
1

Other materials seem to be ok. Only crashes when I apply the Line material to the geometry connected to a subdivided POP.

Hi @Loksu,

thanks for reporting this. Can’t currently reproduce, could you let us know your hardware setup and operating system?

cheers

Thanks for the report, this is the same Line MAT crash as in Palette:gestureCapture error [ 2025.30060 ] - #2 by vincentDev

It was fixed internally already and the fix will be in the next release.

The crash was happening if the POP had primitives or vertex attributes and topology info on GPU, see attached for workaround removing vertex and prim attributes until next release.
