Made a makeshift fix for the black triangle yesterday -
shared it on gdisk if someone wants wants it, drop it into Data\Meshes\enderal\forgottenstories\actors\vatyrs\ - old models are cool but I see that the new model is based on werewolf and seems more fitting lorewise. Grabbed the latest NifScope and changed a few coords:

A proper fix would require more accurate work and messing with textures too (the original ones weren't supposed to be seen withhout the armor parts anyways) but it should solve the immersion breaking prob for now
In case someone want to make it themselves:

The model in question is goatmanbis.nif in Data\Meshes\enderal\forgottenstories\actors\vatyrs\ (can be found in E - Meshes.bsa). Now the game uses only this one model for all vatyr types so editing it should fix em all, open it with NifScope and swith to Vertex selection mode, next select what you want and mess with coords
