Constructor is free. You only have to give them your email address and then you can download it.

Interesting idea. I did not know that milkshape can load and save .map files.

All:
I forgot to mention that Constructor allows to load every arbritary mesh (static meshes as models) into the scene and that those static meshes cast wonderful static soft shadows.

I will show some examples later on.

By the way: Rotating and scaling is so fast in Constructor. All of you who know the in-game editor of Torque already know that you only have to press STRG or ALT to change into these modi. No clicking at buttons necessary. You work with the speed of your thoughts.
You can even rotate in 15 degree steps if you want to make well aligned rotations. Then you have to press Shift wile performing the rotate action.
