Not 3D models, but Adobe Illustrator models. The ramps are just cut-outs of metals, I'm assuming they just a laser cutter; so no models, just accurate measurements (which is what he uses AI for). What I ended up doing was opening the .AI in XNView (InkScape is way too slow), exporting as a png, importing in Sketchup, then making flat, simple planes around the objects in the picture; then oriented things (so for example, the right ramp is really just three flat planes). Exported as a Collada file, imported into Blender, and used Cycles Render.
I then went into GIMP, selected all the white, inverted the selection, and painted black so I could have some very crisp/clean lines. I filled in the shapes with a brown color, added some dirt using the airbrush, and there's the texture to use in Blender. In Blender (again I'm using Cycles), I applied a bump map using the dirt, a diffuse shader, a gloss shader, and a transparent shader (why I have to use that to take out the alpha of the texture is beyond me). I baked out a texture to make some shadows. I may do another bake to get some reflections, but baking in Cycles uses the angle of the face or Normal, so looking straight up from, say, the bottom produces no reflection (since the banisters are perpendicular to the floor); so I would have to angle the banisters to bake a reflection. But I think the shadows look good enough now.
If you want more step-by-step how I did this, I'd be happy to share.
I may have spoke too soon about the sound files. It would seem VP only accepts Signed-Integer coding, which doesn't go down to 8-bit, only 16-bit. So the smallest I could make all the sound files is around 70 megs. Should I just provide the sound files separately and give instructions on how to import them. We're lookin' at an over 100 meg table now.
