If you never heard about Artella.com, you should definitely check it out. It is an online platform that allows you to bring your animation/VFX ideas to live, giving you the possibility to connect with artists spread over the world and work with them on your project in a cloud system.
I was lucky enough that Tim Rudder contacted me via Artella and gave me the opportunity to work on a full-CG animated short that was first shown at the CTN-Animation Expo 2016.
DUEL is the first project that was completed on Artella.com and it looks pretty amazing. Considering the fact that this was done with over 50artist spread over the world dedicating there spare time to bring this idea to live the quality of the final product is just amazing.
But have a look for yourself and if you have some ideas for an animation-short but do not know where to find the people to realise it.. Artella.com is the way to go!
