All right, so I've got this tower I've made using pre-existing textures from the game, but can't seem to load it into the game. I've used Nifscope to prepare the textures and everything seems fine in there, I save it out, and when I try to load it into the editor, I get an error saying this:

C:\_Skyrim\Code\TESV\BSShader\Shaders\BSLightingShaderProperty.cpp Line: 806

I assume this has something to do with how I set up my shaders in Nifscope. But is there a good tutorial out there that provides a step-by-step list of things to do to get an object in game? I've come across a few older ones, but nothing seems to be working for me. Besides the code error, when I import my object into the ck, it's just a blank bounding box, no geometry or textures. I even checked in wireframe and nothing shows up.

Thanks for any help in advance.
