In the company versions from Narron, I removed the animation and skeleton files that fktifzobr@mail.ru pointed out, and the cutscene plays correctly. There were no xdb animation files in this version of the mod.
There are several versions of mods for all campaigns, and the fix needs to be made in such a way that it is compatible with all other mods and does not affect the game, in this case, the Tribes of the East. Tinkering with the mod is not an option. In fact, this red glow is insignificant (compared to what has already been fixed). Perhaps other bugs will appear and be resolved later.
