Camera culling not working?

DrGonzo62

Hi,
I'm working on a scene and I'd like to reduce Cycles render times by hiding objects that are not visible in the frame.
I enabled camera and distance culling for all objects in the scene (ALT-Click), and also enabled Simplify / Camera and Distance culling in render prefs.

However, it doesn't look like Blender is culling anything.
When I manually hide those objects instead, my render times drop significantly, as expected.
And btw, all those objects are individual meshes and not just part of a single large object that would remain visible because parts of it are still in the frame.

So, does this feature simply not work at all? Or am I doing something wrong?

Thanks!

The steps you did seem fine. Tried with some daz scenes and works fine here, unless there's a issue with the specific scene you're using. However it is easy to see how it works as it is interactive in the viewport. Just set the viewport to active camera and rendering to cycles, then activate the culling. Cycles will only render the objects inside the camera.
