--------SOLVED------- So I did some more experiments and I have located and FIXED the problem. Here's what was going on: - The new building mesh is fine. (no issues there, everything was set up properly before exporting from Blender) - The normal map was built correctly. (it works as intended) - The Layer Mask on the alpha had a black layer applied to eliminate plastic like glossiness (This was not the issue as I had previously thought) - It turns out the problem was with the actual texture itself being to bright.(Not the normal map) I'll explain further, and tell you what I did to fix it. Below is a couple pictures showing 3 buildings. Two vanilla buildings, one with a dark texture, and one with a light texture, and my new building mesh and texture. In the upper left picture, you can see my texture closely resembles the shine effects present on the side of the vanilla light building. And the dark building has none! Hmmm...... this got me thinking, maybe my texture is to light, I need to darken it up. This is what I did to fix it: - Opened my main texture in Gimp(not the normal map) -Under the Colors tab I chose "Brightness-Contrast" - I then pulled the brightness slider completely to the left making it as dark as it would go, then clicked OK -Then I exported You can see the results in the far right of the image below. http://newvegas.nexusmods.com/images/1520317-1361950398.jpg
