There is a 100% crash in Material editor. I’ve attached a project and a screenshot.

The best contact persons for the issue in Epic are probably Jeremy Moore, Chris Waters (the authors of these nodes)

Hi Oskar,

Thanks for reporting this. The issue should be fixed by perforce change list 44785098 in UE5 Main.

Note that we don’t currently support any material texture streaming analysis for Texture Collections.

So the Record Texture Streaming node will also do nothing for these.

Thanks again and best regards,

Jeremy
