I'd like to try some 3D modelling, sometime.
Are you using public domain software, or expensive professional package?
blender, it's free, but a bit of a pain to learn.
There are a lot of instructionals on Youtube though.
And recently I downloaded the free version of Unity, but I started with that two days ago to see if this project is useable.
A much easier program is Trible's Sketch Up.
But I've just stRted this as a hobby less than a year ago.
