License

The code

Marble Studio's code is released under the GNU General Public License, version 3 or later (GPL-3.0-or-later), like Blender itself. The Python source is in the zip you install.

The lighting image that comes with the add-on, "Glasshouse Interior" by Poly Haven, is CC0 (public domain). It is credited in the add-on's CREDITS.txt.

Seats

Marble Studio Pro is licensed per seat: one seat per computer you use it on. It works on an honor system: no license key.

Marble Studio Free needs no seat. Install it wherever you like.

Updates and support

Every purchase includes 12 months of updates and support. Everything you download in that time is yours to keep.
