I'm trying to render an animation in C4D R16, and the render randomly freeze (sometimes on frame 2, sometimes on 98, on 15 and so on) and the render status of the frame is at the freezing time "Shadows BiRender" ("BiRendu Ombres" in french).
Shadows BiRender part happen just after the line rendering/calculation (from sketch tags) and just before it start to actually render the image in the viewer. When there is no problem the Shadows BiRender part took less than 1 or 2 seconds.
never add this problem before, I've rendered much heavier scene, this on isn't that huge, quite a bit though, but only an average of 2 minutes 30 by frame to render.
about the scene, there is :
- some sketch tag on several object
- some cell shaders type materials
- hair dynamics
- no GI
- standard render (no physical because incompatible with sketch post effect)
I can share the scene file if needed as it's a personal project, but it's quite heavy (66 Mo)
does anybody have an idea of what can possibly goes wrong here, or what should I check ?
