Since the last blog post, the dev team was working on several issues reported by branch users. Two bugs causing a crash of the Freestyle renderer were successfully fixed, thanks to the provision of a .blend file by Cloud_GL for bug hunting. One of the bugs was related to the use of movie file formats such as AVI, QuickTime, and FFMPEG codecs. When one of these movie file formats is in use, animation rendering with the Freestyle renderer enabled was very unstable. The other bug was in the Resampling shader for changing the spatial resolution of strokes. Since the Resampling shader is widely used in standard style modules, the bug must have caused a lot of trouble on the users side.
Soon after the instability issues were addressed, several branch users kindly reported that the branch is more stable than ever and now is capable of rendering those .blend files that previously cause a crash. We really appreciate the feedback, thanks!
In the mean time, Stéphane, one of the developers of the original Freestyle, sent us a link to a movie clip for introducing Freestyle. The movie clip was screened during the Technical Papers Fast Forward session in SIGGRAPH 2010. The entire movie clip was made using Blender and Freestyle. Thank you Stéphane for sharing the nice video!
