I recently downloaded Houdini Apprentice and have fallen uncontrollably in love with it almost immediately.

So, I'm now looking to upgrade to Apprentice HD to allow me to render in full HD. 8)
Could anyone advise if there's anything major / significant limitations in the HD package (in comparison to Master etc) other than 2k / 4k exporting?
Basically, I'm wondering if there's any limit on the amount of frames that can rendered from 1 project, or perhaps file types that can be exported etc.
I'm pretty new to Houdini and the 3D world, so bare with me if this is a typical noob question, but will I be able to export 3D objects and camera data etc to Nuke for compositing? Or would I need the Master package to achieve that? (Out of my current budget atm).
Huge thanks in advance!!
