[Bf-committers] Blender developer meeting notes, February 9, 2014

[Ton Roosendaal]

Hi Nathan, Bassam, etc etc.

To prevent this topic to get lost in the avalanches of emails here, let's consider to re-activate the bf-animsys list for it.

http://lists.blender.org/mailman/listinfo/bf-animsys

That way things get a bit more condensed and coherent. I'll make sure that the devs who will do animation coding for Gooseberry will report on that list and use it to validate their todo lists, planning and designs.

Might take a month or two - we have to do a fundraiser first still :)

Laters,

-Ton-
