Fixed: uploading .udceab files from old Unity versions, as well as, sometimes, from new ones, returned a character with black textures.
If you still encounter this problem, please report it to the forum.
If you have problems with the new version, you can upgrade to the latest stable version:
- Find the app in the Steam client
- Click LMB
- Select Properties
- Go to the “Betas” tab (usually the last one)
- Change "default" to "stable"
- Save the changes and wait for the update.]
