[Irritating issue] and Question about Reflectivity

Post » Thu Feb 14, 2013 12:53 pm

First let's begin with the irritating issue: I successfully converted My model I made into Skyrim. Although the textures won't appear until I re-apply them through Nifskope. Without the Textures, here's what it looks like:

^ It doesn't glitch or anything of the Sort. Works fine. Although, we can't be having a model in Skyrim without its textures, now can we?


However, when I apply the textures, then save it in Nifskope, this is the result that happens in the CK

This only happens if I apply the textures and save it with Nifskope. Which originally, I've never had this problem when using Throttlekitty's Rc1 version of Nifskope. [meaning I have successfully applied the textures and saved it with Nifskope, and it worked perfectly fine in the CK afterwards, in the past week].

I've tried re-downloading and re-installing Nifskope as well; that didn't work. I've also tried applying textures and saving it with nifskope without getting errors, using both multiple custom made models of mine and already made models of other people, testing-wise. Still didn't work.

I don't know what the problem is, considering there is no error reports anywhere for this, and nothing pops up saying there is an error, it just happens.

This is just more of a technical how to Question:

When I make custom models, I add the base texture and the normalmap as well. For instance, " Plaster_wall_01.dds and Plaster_wall_01_n.dds" is applied to a model I make, but in-game, it comes out super-reflective or glossy, such as:

http://i1112.photobucket.com/albums/k481/kenders21/Modding%20issues%20Album%20display%20of%20problems/Reflection_Glossissue_zps19dc0cdf.jpg

I don't yet know how to fix it. I thought about applying a envmap, or "Plaster_wall_01_m.dds" to the model, and tried the way I know. Didn't work. And the sliders in Nifskope that allow you to control such a thing, aren't there, unlike they are for Morrowind Nifs.

So my initial reaction was to look into the Skyrim Textures and look at the envmaps for Architectural models. I saw absolutely zero. only, normalmaps and base textures were there.

So does Skyrim use envmaps for non-reflective surfaces? Are these envmaps different then Morrowinds black and white version of the Normalmaps?

And are there any tutorials specifically aiming at detailing working with envmaps in Skyrim, and reducing reflection and gloss?

Specular data (glossiness/shininess, as distinct from reflectivity) is carried in the alpha channel of the normal map. If your normal maps have no alpha channel, the game interprets it as pure white, resulting in highly glossy and shiny surfaces.

Look at some vanilla normal maps as examples.

ok then that part is different with Morrowind. Any idea on why the nifskope acts the way it does?
