as a followup. I have seemed to resolve a lot of my issues with fixing my namespaces.

I am having similar issue in maya 2024. Rebuilding hangs up at 45% : # File "C:\ProgramData/Autodesk/ApplicationPlugins\rrm3\Contents\scripts\control_rig\rig_post_build\rebuild_rig.py", line 630, in save_animation_data # cmds.file(atom_file, type='atomExport', exportSelected=True, # RuntimeError: Could not save file "C:/temp/lucy_RIG_assett:lucy_rig__rebuild_anim.atom".

Thank you and I thought I should ask anyway. For anyone wondering, rigs with RRS2 and RRS3 together in a scene work perfectly well.

In referencing my asset rig, I have checked 'Use Namespaces' and the 'Merge into selected namespace...' in the options. That was the only option that seemed to work to display my saved rig layout from my asset. Maya seems to strongly suggest I use namespaces. Is this important?

Works perfectly now and I probably should be more mindful of namespaces. Making RRS layout changes in a scene with my referenced rig is probably not a good habit anyway, but now this is great because I can apply the saved .rm3ui file back to my original source rig. Thank you again for the great product!

thank you and I emailed: info@rapidrig.com

I was able to duplicate the error and it seem to have occurred after I arranged my buttons in a tab and saved the .rm3ui file. After that, I when I launched the RRS I got the division by zero error.

hey Justin. Long time RR user and was very happy to see that you have version 3 out. I kinda freaked out when I saw the new RRM selector interface. It's a lot different. But Im starting to see how it works and how much more powerful than the previous versions. This is a brilliant program and looking forward to the tutorials so I can get the most out of this program.
