Three questions

[Mine Turtle]

the editors are twitchy. id recommend for you to make your models in maya, or 3ds max, and export them as .dae's from there. otherwise you might have some unwanted issues.


there is a student version of maya avalible. its free of charge, with the exception that you may not sell your models or any other content made by it.

hope this helps, i really wouldnt recommend sketchup, but if it works for you, its alright. i just recommend maya if you dont want to struggle with modeling. ^^
