Hey there Arran,

Badger's right about the upgrade policy.

About when to upgrade.... any industry is competetive so if you're using Maya as a business tool then it would be wise to upgrade with the competition, you don't want to lose out on a contract because the company next door has the means to make a model/animation which you would struggle with because your tools aren't quite up to the job.

If you're using Maya as a hobbyist then there's no real pressure to upgrade. Learn what you can and when you feel it's time to move on then go for it.

Out of choice I would still be on Maya 7 if not for university and the fact that I want a job at the end of my studies.

That's my ramble anyway,

take it easy,

Mat.
