The short answer
Free and open source. Both halves.
There is nothing to buy and nothing to ask about. Use the player anywhere,
use the add-on for anything, and keep what you bake.
Which applies to you
Every case is free.
- Free
- You baked .lerpa files and want to use them anywhere, including in
a product you sell. Baked artwork carries no obligation from this project
at all. The output is yours.
- Free
- You ship the web runtime in anything: an open-source project, a
client site, a closed-source product. It is MIT; keep the copyright
notice and that is the whole of it.
- Free
- You use or change the Blender add-on. It is GPL-3.0-or-later:
a copy you have is yours to modify and pass on, under the same terms.
Why two licences
MIT where it can be, GPL where it has to be.
The web runtime — MIT
The player ships inside other people's pages and products, so its terms
should never be the reason to pick something else. Versions up to 0.4.0
were AGPL with a commercial licence; from 0.5.0 it is MIT.
The Blender add-on — GPL-3.0-or-later
It links against Blender's Python API, so it is GPL and permanently will
be. The source is public and the add-on is free.
