First I want to say this is awesome work and That I can really relate on the quantity of effort you are putting in to this. I am currently building models texturing them for a game of course they are far lower in poly's so they are no where near the depth and detail you have put in. So by the way once again AWESOME JOB!!!
Now a question that I think you might be running into as well as what I have been running into. Scaling! Do you find it that the some of the Stats Of the SDF 1 are not matching up? I noticed when I put my models of the VF-1 in with my SDF that the SDF is really small and to get on screen comparison I have to scale the SDF to almost 3 times its size as stated in some sites. Are you running into this problem as well?
Also I wanted to ask what kind of rendering programs you are using?? Because I am still mainly just use a game engine to render my work or my model viewer that comes with my software.
