Free and Cheap versions of Houdini

Houdini Apprentice has been available for some time, providing a free but non-commercial version of Houdini procedural animation without cost (but with limitations).

Recently, SideFX added the "Starving Artist Edition" to the apprentice program, providing HD-capability for animations (1920x1080 pixels) and watermark-free rendering. It will cost $99, which is cheap compared to the full commercial prices.

It uses the same non-commercial file format as the free apprentice edition and is not usable for commercial purposes.

Available for Windows and Linux.
