Material Editor Problem

[Mudbill]

You're talking about the normal maps and specular maps applied to the texture. Yes, when you load the model in the Model Viewer, it will automatically detect textures with the same name with included extensions of _nrm or _spec etc. It then creates a .mat file that already has those applied.

If they do not show up in the game, firstly make sure that when you open the .mat file in the Material Editor, that these textures are actually added. Otherwise, if you only have a box light in your level, the maps will not be visible, because they react to light traveling across the diffuse texture. Box lights are ambient, in other words, the light is applied equally from all directions, therefore no reflections or bumps are added. Try looking at them using the lantern, or have some point/spot light somewhere.
