Sponsor the development of a specific feature.
It can be a small bugfix or a large feature — just propose anything that you actually want to see implemented. If you want, you can pick one of our larger planned features.

The websites linked above are easy to use, and the others get an opportunity to comment on the project, co-sponsor it, maybe even just take the job themselves :) Just post a project there, and drop me a mail about it.


I'm Michalis Kamburelis (email, google+). I'm developing this engine since 2007, with a dream to create something great and open-source and (forever) free. I guess I spend most of my days (and nights:) developing it throughout these years.

Since 2016, I don't have any other job, and I devote 100% of my life to extend this engine and create games around it, as part of the Cat-astrophe Games studio that we formed with a friend! So I'm really crazy about making cool games and keeping the engine growing and open-source:)

So I really depend on your donations. Even a small donation matters a lot to me. It allows me to continue to improve the awesomeness of our engine, and view3dscene, and our games. Thank you!
