If you use Community Shaders and its addons and Deadlands Xivilais- Mihail Monsters and Animals, you may have noticed the skirts on them are not looking correct.
This fixes that problem by removing the Environment Mapping shader from the affected parts of the meshes.
I think this has something to do with CS lighting as this issue goes away if you turn that off, but I'm not expert on that and its only an educated guess.
