The peach team has just posted a thread asking for external help for a coding project
Please refer to this
Taken from the thread
We are working hard to define the last version of the story by the animatic now, while the coders are refining great new features to be used in the movie.
Btw, Brecht, Ton and Campbell are too busy with a lot of new stuff at the moment and they have a priority list to work on, and because we could need volumetric clouds and realistic sky generation for a few shots, this post is meant as a call for help by external coders who can offer a good code for this.
