Cannot import characters wearing the Biker Vest from the "CC3 Outfit and Accessory" pack.

[jdavies]

Steps to reproduce:

1. Open CC3
2. Open the "CC3 Outfit and Accessory" pack.
3. Add the "Biker Vest.ccCloth" to the default characxter in CC3.
4. Export the character as an iAvatar using the default values (ie no LOD)
5. Open iClone 7.9
6. Import the iAvatar into iClone.
7. Select the character in iCLone and export as FBX. I usually uncheck the "Embed Textures" and check "Delete Hidden Faces" You can select current frame or range.
8. Open Blender 3.0.1 (I dont think this is version specific to Blender)
9. Using the CC3 addon for Blender, import the character in FBX format.

The following error message appears in the Blender Info Log:

Python: Traceback (most recent call last):

location: <unknown location>:-1

Note: I have only found this to happen with the biker vest, not with any other assets in that pack. From the stack trace it could be argued that this is not a CC3 addon error, but an FBX import error. However, I encountered this via the CC3 addon and it only happens with this biker vest model. I'm posting it here in case you know of a better place to post it.

Thanks, as always!

The UV map in that Biker Vest is completely broken and Blender won't have anything to do with it.

There are some sample characters wearing the vest that aren't broken, if you want a version that works in Blender, you can save the vest out in CC3 and re-use it.

Sweet! Thanks for the tip!
