We believe in an open source approach to the production tools. As such we share part of the scripts we develop for free, as long as you give it proper credit in your projects, including Disnosc's logo and the author(s) of the script.
For now, those tools are all hosted on TVPaint's forum (you need to register to download them).
We are working on creating for them a proper documented place on those pages, as well as adding the tools that are missing.
Proper open licensing, brushes, scripts, and solutions for other softwares are also planned. We can also build tools for your studio.
