Is there going to be a cost for conversion of project you made with Houdini HD?

Is it legal if I use Houdini HD to learn while working on my personal indie project, and only buy it after I have enough money, even if it's mean that would be at the end of the production, of maybe, two years?

Would the conversion is free if I have two years worth of stuff to convert?

NOTE: I plan to make a one man 3d animation, ala Flat World, Idiot & Angels, Romeo & Juliet : Sealed With a Kiss.

Check the Apprentice-page. They state, that they will do a one-time conversion of all your stuff once you purchase your commercial license.

thanks for the answer, although I hope “one - man - full length - feature - animation” full of stuff won't bother them too much :-)
