Specular Texture Editing Problem

[Tilarta]

I am getting close to finishing my custom objects in my new mods.

However, one issue keeps preventing me from finishing the objects:

There are odd shadows across the tile when viewed from an angle or in low light areas.

And with the other object, it puts divots in the texture when the same condition occurs:

I have been told this is a Specular problem, but editing/creating the new Specular map did not seem to achieve anything, as it is still using the default Specular.

I followed the steps here to make the new Specular texture:

Specular Maps

However, I am uncertain that it worked, since when I preview the Specular texture with the default tool, it is completely black.

The normal speculars are a liliac shaded version of the texture.

That's why I think it failed to generate the file properly.

Does anyone know how to fix this?

I have edited the BGSM and the NIF files to point to the new Specular Textures.

The only file not edited so far is the N file.
