Steph use a free real time engine http://www.ozone3d.net/hyperion.php?lang=2 and is creating a plug for C4D
something like that :)
http://stephlx.free.fr/HyperionProjet/hyp4d01.swf
for have easy way between C4D (lights, textures... etc) -->Hyperion
But all objects are created in Moi (because it's so easy :)
But all of course must be transformed in Obj format in Moi
If transformation Nurbs / Obj/ Normals/ Coordinate UV can be made directly in Moi that will be more interesting!
Some many times win !
Yet Now some "basic Volumes" seems have UV in Obj format in Moi :)
