I read
Enables environment mapping. Should be in both the children list and effect list of the NiTriShape object. For Morrowind: the bump map can be used to bump the environment map (note that bump map is ignored if no NiTextureEffect object is present).
I, of course, have no idea what any of that means, except the fact that I need to add some NiTextureEffect property/node somewhere, I think.
Could someone slowly explain me step by step what to add where and how to add that glow on windows? Btw I have Nifscope 1.0.4 if that matters.
Thanks in advance!
