Remigiusz, then how about incrementing a global variable each frame? Can a new instance wait one frame and then actually launch if the value of the variable hasn't changed?
Anyway, seems like I'm the only one responding to this thread, and I'm in no way an expert... Have you tried to ask main developers in the IRC directly? P.S. As I've learned recently, in 2.63 (or maybe even 2.6+), there are bpy.app.handlers.scene_update_pre and bpy.app.handlers.scene_update_post -- these event handlers are invoked each frame (not sure if this behavior will persist, though). It's possible to get the list of the handlers, so I guess in recent Blender versions your idea can be implemented. _______________________________________________ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
