Ok, this will be my first project.  Besides Blender, I'm also looking at
OpenFX (  Unfortunately, I'm a coder not a graphic artist.
I can't say I'm too learned on how to create bezier patches using either
program, so I'm going to have to do a bit of research before I even start
this.  If there are any artists out there with some input (especially
something like "Blender doesn't support bezier patches") I'd love to hear
from you.  Hopefully it shouldn't take too long to make either a file
translator or some kind of export plugin for one of the apps, once I learn
how to make the content using one of the aforementioned apps.

Right, this will be phase 2.  I was sort of expecting this to be the hard

Can you elaborate on this?  Are you talking about coming up with some kind
of algorithm to color the geometries instead of using textures?  I don't

Right, I'm assuming that once the .zone files are generated, I can follow
the process used with 3DS Max.

Thanks for the feedback Cyril.  It's nice to see how much input the official
team has on this list.
