CC4 character UVs are distorted
I'm using language translation.

1. Move Toon Neutral_F.ccAvatar to Blender using the pipeline in CC4.65.
2. Add a new material to “cc_Base_Body” in Blender.
3. Assign the new material to some mesh part of the Body, e.g., part of the forehead.
4. When returning to CC4 via the pipeline, the UVs are distorted.

Attached are screenshots showing the appearance in CC4.65 and the UVs checked in Blender.
Additionally, this occurs even without adding a new material. The steps are as follows:

1. Move the Toon Neutral_F.ccAvatar from CC4.65 to Blender using the pipeline.
2. Edit any UVs and split an island.
3. When moving it back to CC4 using the pipeline, the UVs are automatically merged.

Attached are screenshots showing the head UV island after splitting and the UVs after moving to CC4 where they were automatically merged.
I confirmed this occurs in CC4.65 and 4.64, but I believe it did not happen in CC4.62.
This automatic UV modification is extremely problematic, so please fix it.
