[Bf-blender-npr] priority targets for Freestyle and Blender NPR capabilities

[Ton Roosendaal]

Hi all,

Could the frequent NPR artists here feedback on the todo for Tamito?
He's on an extended contract for the development fund, and I like to see his work well supported by as much people here. I can see why it's interesting to have Cycles render strokes, but I never would have thought it's a priority for anyone.

I also thought everyone liked to see more work done on quality rendering for NPR (material options especially). Blender Internal is very much ready for that.

I specifically asked NPR artists from studios (Kampoong, MAD Naples, etc) to get involved. Where are they?

Lastly: the 'beer' project, where are they? This is a chance to get features handled and worked on. 

Thanks,

-Ton-
