So I would like to understand the process of adding bump maps properly in Nifskope
I have this cuirass right here &already existing reflect maps:http://img7.imagebanana.com/img/vyf0gf4e/glassixp.jpg
So I made the entries for the normal maps but I guess I didn't understand Block ->Insert->NiTextureEffect...
Does any NiNode need that effect added?
Would really like to know that, but I'm pretty new to this...
Is there someone who could help me?
Didn't find any tutorials.

Right click on "NiTexturingProperty" for any Block, it will present a list with "Textures" at the top, select that and you'll be able to add any kind of "map" you want.

Hope this helps.
