Morrowind and Freedom Force use the same graphics engine. Nif 4.0.0.2. Freedom Force supported gloss maps. That was, the ability to make a flat looking texture simulate reflection. So that polished leather might 'shine' without having to texture it to look like shine. (with standard art techniques used by good artists everywhere).
I was confident Morrowind also used gloss maps. The hated plastic wrap of enchantment, looked exactly like a Freedom force gloss map gone wrong. The usual mistake is to misname the gloss map texture, which controls which parts of the mesh reflect. With no texture, you get 100% reflection everywhere. The engine substitutes a simple fully white map. No mapping at all.
I looked for the gloss map for enchantment (to go with the caustxx files) but there wasn't one.
I examined the executable in a hex editor, trying to see if the simple map was created on the fly. No dice.
I made the slight configuration changes to Morrowind Nifs (in Nifskope - texture paths must be changed) required to view them in the Freedom Force Nif viewer and created light nodes, NiTextureEffect nodes and textures, and gloss maps and textures, as if Almalexia was an FF model. It worked! She glossed where I wanted her to!
Converted back to Morrowind. No dice. She glossed everywhere. No map. I wanted her clothes to shine but not her skin.
Came to the conclusion that Morrowind was NOT honoring the gloss map. That is throwing it away unused. The 'texture count is 2' messages I got with my Almexia made sense. It was finding my gloss map and throwing it away.
This is why people think a skinned mesh cannot have a gloss map.
I asked for the behavior to be traced and optionally disabled, which is now possible in the superb code patch.
Hope that explains a bit. Ask if that raises more questions than answers. Googling for freedom force and reflection and maps usually gets tutorials that explain how they are used. Remember, both games are different but use the same graphics engine, down to the version number.
So prior to the codepatch, it WAS impossible to use a gloss map in any meaningful way. Now it can be.
My Almalexia now has matte skin but glossy metal clothes!
Final edit: I will try to release some demonstrations to showcase the technique, but real life is tough at present. I resigned from my job on Thursday - a drastic step but I needed to for my sanity! (grin)
