Nifskope seems to render the gloss effect on certain vanilla nifs, even when certain data necessary for custom or reexported nifs to have gloss effect, is lacking. I am using full released version of Nifskope 1.1.0 & Blender 2.49b (other programs used listed in my Niftools forum post, under Nifskope subforum).
I\'m talking about the rendering in Nifskope, and have not checked the effects ingame – yet. Also, I took the screenshots with the Nifskope setting adjusted to “Nighttime” lighting.
CWEntrance01a.nif (vanilla nif) -
In pic #1, this is a vanilla nif, that has not been reexported from Blender, though it has had textures changed whilst in Nifskope. It does not have a NiSpecularProperty, and the Specular Color in the NiMaterialProperty is set to pure black. The stalagtite exhibits glossiness, as you can see.
CWEntrance01a_KP3.nif (tweaked and reexported from Blender) -
In pic#2, the NiTriShape in question for the same stalagtite, has exactly the same properties, with same settings – everything is the same as in the above vanilla nif (I have quadruple-checked). But it shows no glossiness, like in the vanilla nif.
CWEntrance01a_KP3v2.nif (tweaked/reexported from Blender, has some Nifskope changes) -
In pic #3 & #4, everything is the same as in pic #2, EXCEPT for the stalagtite NiTriShape in question, I added a NiSpecularProperty with Flag set to 1, and set its Specular Color in the NiMaterialProperty to pure white. This reexported nif is now glossy.
I will include the related nifs and textures in a download.
