Hi guys,

when I load a .blend filke created with build 47fcd0881d22, my console shows several errors. Any ideas?

‌

Cheers,

Peter

Sounds like a Blender bug. Are you running an unstable build?

Blender 3.2.1, E-Cycles Build 7th July. And it happens in vanilla too. (Just checked)

I got a bit more info:

ERROR (bpy.rna): C:\Users\blender\git\blender-v320\blender.git\source\blender\python\intern\bpy_rna.c:7392 pyrna_srna_Subtype: failed to register 'DAZ_UL_CustomMorphs'

I just downloaded the 3.2.1 release for Windows 7 from https://github.com/nalexandru/BlenderCompat/releases and loaded an old file. It loaded without problems, but there were some warning messages in the console that may be related, like

register_class(...):
Warning: 'DAZ_UL_Custom_Z PAH ' doesn't have an alpha-numeric suffix

‌

[Thomas Larsson]

In the last commit only alpha-numeric characters are used in UIList names. That removes my warnings at least.

Thank you Thomas, with the latest build the problems are gone! Will close this issue!

A newer build fixed this issue!
