Well, after about 5 minutes of troubleshooting, I got it working in game. I'm not sure why I assumed the material would carry over. But it probably wouldn't even take a separate guide. Maybe just another paragraph. Ty for the guide. Now I just have to do it all again, except with the _01 this time.
On a side note, it's MUCH easier to simply copy branch the BSLightingShader and the BSShaderTextureset from the original amour, and then paste them in the new one, rather than adding new ones and editing.
As a side note, sometimes when I hit alt P, it pops my blender window into blender game engine, and then blender freezes. I'm not sure why, and fortunately, I save my work often. Just thought I'd post that error, so that if other people have it, they see. It's easy enough to go to obect/parent, and do it from there.
