Hi, I noticed a crash when exporting .usd in Blender 5.1.2 when using ZenUV 5.3.3. (Narrowed it down by repeating the same export toggling plug-ins on and off, and getting 100% reproduceability of the crash when turning ZenUV on and off). To continue working I need to roll back to a previous version. My question is twofold: 1. Are you aware of the bug, and are there plans to fix it? 2. Where can I find older versions of ZenUV? I purchased it on Superhive but I see no legacy version download options. Preferably I'd have the latest version that does not produce this crash. Crash log attached. https://cdn.discordapp.com/attachments/1518556416367923363/1518556416615383220/Zeebrugge_Unreal_Buildings_v01.crash.txt?ex=6a3b021f&is=6a39b09f&hm=7df754d9524d339d94800be55cd5796301faab99445b0a553d70aead8c346859&

Hi, I can not confirm the bug. I downloaded the file from our example list, selected all objects and executed USD Export

Thank you for your response. After further testing I've also had succesful exports with ZenUV 5.3.3 enabled and had others fail with ZenUV disabled. However there does seem to be a strong correlation between the crashes and ZenUV. Just had 10+ succesful exports with it disabled, turned it back on, instant crash on export. It seems the crash occurs when I export a specific set of meshes on which I've done a specific ZenUV set of UV operations when only exporting selected objects and overwriting a previous .usd export. I'll investigate further, thank you for your time!

According to your log the problem is in depsgraph, you can completely switch it off in ZenUV by disabling this option:

Cool, will try the problematic mesh selection again with this on/off and report back. Thanks!
