Posted this in main chat and was told this was a layering issue. The brindle pattern on this RID does not fit correctly on the model.

I didnt do anything in particular to create the bug that i know of, was just clicking through my stables and thought the pattern looked off. Got some feedback from other members and they said it was a bug

Managed to find a similar thread with the same issue.

Seems to be only one pattern of brindle that does not fit

the issue is that it is trying to layer the AA brindle over the RID base, but has to be flipped(You can see the base of the AA tail on the brindle layer) I believe :P

This has been an issue for a while, sad to see there has been no response.

Fixed, thanks!
