I've got an object that shouldn't be included in any raytracing, yet mantra builds an octree for it. It's a pain as it's octree calculation seem to take infinite time on a certain frame. Other octrees goes fine but on this the render stays, with RAM usage frozen and one processor on full speed.

It's name doesn't match the shaders raytracing “Object scope” and I've unchecked “enable raytracing” render parameter on the object. I've changed KD settings and switched ray-tracing accelerator but no luck. I DID get it to go through once when I moved the camera but not when I moved the object itself. Understandably, the camera need to be in place so that's not a solution.

Any ideas on how to skip this octree calculation or pushing it through would be appreciated.
