We are in the process of merging the code base with the 2.5 branch. We have prepared two documents on the wiki, outlining the current status and an overview of the engine internals, and a FAQ on the blog. The FAQ and status report are meant for all users. Please take the time to read it, it might answer some of your current questions.
We hope to start merging this week. We are still waiting for feedback from the core Blender developers. It is important to note that development will halt on the Blender 2.48 branch. This might cause some interference with your work in the next few weeks. We do think moving on to the 2.5 branch now is better in the long term for all of us. We are sorry for the upcoming problems you might experience.
As Freestyle will be integrated in the main branch, we think it is an opportunity to rename it. “line strokes”, “line rendering” or “line drawing” are possible names. Let us know if you think of a better name !
The thread has also been quite busy recently (samples from devroo #515 #523 and pyroserver #530 #556, combination with ‘Painting with Polygons’ technique…). We have seen the showcase of fantastic artwork by blendman, a French artist involved in the Moonkiroe MMORPG. As you can in the thread (#543, #550, #552, #561), blendman has utilized the Freestyle engine to recreate bande dessinée, a comics style used in France and Belgium. The results are simply breathtaking. Thank you blendman for sharing your work and your expertise with the rest of the community !
