Of course you can! My guess is that you haven’t loaded the plugin in the new scene. CUAs exported with this plugin also need the plugin to be loaded in order to import them.
ldfec updated [PersonToCUA Motion ]Character Export, Animation Recording & Playback with a new update entry:
Fix some issues with exporting 4K textures and add a naming feature.
Read the rest of this update entry...
Several users have reported errors when exporting 4K textures. Some issues were related to hair, while others were caused by specific clothing items. I've fixed as many of these issues as possible. If you still encounter any errors, please send me a DM or let me know in the discussion section...
I didn’t notice this reply earlier, but if you want to upload it, go ahead. Your approach is different from mine, so I think it would definitely be better if people have more choices. Thanks for continuing to push this plugin forward.
All CUA-based hair and clothing are excluded from the exported model. I've never used CUA hair or clothing myself, so I can't give you a definitive answer. You could try testing it yourself.
My guess is that you didn’t load this plugin on the new CUA. You can try it again. I didn’t want you to wait too long, so I tested it myself, and this is very likely the reason.
I achieved the saving functionality using another plugin. If you're interested, you can go check it out there.
