Occlusion culling settings

Occlusion Culling Settings
Occlusion Query Enable an additional hardware occlusion query test for all objects with the Culled by occlusion query flag set before sending data to the GPU.
Frames Number of frames required for the occlusion query update.


Occluders Enable or disable rendering of occluders.
Resolution Resolution of the texture, to which occluders are rendered. The maximum resolution is 1024x1024.
Shadows Culling Enables occlusion culling for shadows. The option should be enabled, if you need to disable shadows rendering for the occluded objects
This option disables shadows from the world light only.
By default, the option is disabled, as sometimes shadows of the occluded/culled objects remain visible even if the objects aren't.

To toggle occlusion culling for shadows via the console, run render_occluders_shadows 1.
