Hello there, I am currently a student of animation in the UK coming up to my third year. After getting to grips with zbrush using the free trial this summer I feel disadvantaged not to have it during my academic studies. I am Just wondering if Pixologic have a student discount scheme? Additionaly is it true that once you have payed for one copy of zbrush you get free copies of subsequent versions as you are paying for the lisence mostly?
Thanks

Education:
Pixologic’s partnered resellers (see the Academic heading at http://www.pixologic.com/resellers) provide two kinds of educational discounts, depending on your needs:
Individual students and faculty can receive a discount on the single user license, which may be activated on up to two computers provided that both copies are not actually used at the same time. This copy of ZBrush is full-featured with no watermarks or other limitations. It is also able to receive any free upgrade offers that Pixologic extends, with the license remaining an academic license after the upgrade. The only limitation is in the license itself, which allows ZBrush to be used strictly for non-profit/non-commercial purposes. An individual academic license may be upgraded through Pixologic Support to a full commercial license at any time, receiving a discount of 50% off the current commercial price at time of upgrade.
Institutions requiring five or more seats may receive an academic license under the volume licensing system. Under this system a number of seats are purchased equal to the number of workstations on which ZBrush will be installed. There is no home use option. All copies of ZBrush share the same serial number, making it easy to manage the license in a classroom environment. As with individual academic licenses, these are for non-commercial use but they may not be upgraded to a commercial license at a later date. Bulk pricing is available with most resellers, with discounts increasing at higher quantities. After purchasing a volume license, additional seats may also be added to that license at a later date, with no minimum quantity required. As with the individual academic licenses there are no software limitations and these licenses are also eligible for any free upgrades.
Pixologic does not charge for technical support, there is no need to purchase a separate service plan for our software.
All updates so far have been free. They have not said that all updates in the future wil or will not be free though.
Amazing! thanks a lot
