How to utilize OBMM.This page updated on May 29 2017 CST
This tutorial will demonstrate how to create a shiny and reflective effect for your weapons and armor.
It's a matter of making the armor (or weapon or other item) like that of glass. The effect is controlled by settings inside NifSkope (tested on NifSkope 0.9.8 thru 1.0.6). You'll then need to tweak the diffuse texture (a.k.a. Color Map / Texture), normal map and it's alpha channel to make it look good. Generally, when you just change the NIF properties, you don't get the best effect. Jerros and I learned the initial steps to create the effect by Vagabond Angel. But knowing the steps is a far cry from knowing how to make it look good. It's a game of tweaking, balancing, and re-tweaking that is more of an art than science to get it to look right.
Even when you get the armor to look good, you'll then need to tweak it even further to make it look good in daylight (not too bright), inside buildings and at night (so it doesn't look like unrealistic shiny plastic).
If designing the model, it is best to in mind that the shiny metal should separate objects (NiTriStrips/Shapes) from the non-shiny pieces. This allows for separate material properties and is much easier to control for non-shiny pieces.
Use this chart as a guideline for the color of your diffuse texture.
It's also important to note that the reflection map this technique uses was changed between Oblivion 1.1 and 1.2 patches. So if you tweak your armor for version 1.2, it will look different on machines without the patch or running version 1.1.
The texture file that controls the look of the reflection map is Textures\effects\windowenvironmentmap01.dds. It is recommended that you do not change this file since it controls ALL environment reflections. If you'd like to create an alternative, I'd recommend doing it as a standalone mod that can be used as a recommendation to other mods that use the reflection technique rather than a requirement.
If the video option in Oblivion called "Window Reflections" is turned off, the armor will look completely different and usually not very attractive.
If you use this technique, be sure to credit Vagabond Angel for the original technique and then Jerros for the additional information. I do not need credit since they are the ones that figured out the majority of it.
