bentNormals property
Also computes the bent normal (the average unoccluded direction) and carries it with the occlusion. Indirect diffuse then samples irradiance along the bent normal, so occluded surfaces stop picking up light from directions that are blocked, and SpecularAmbientOcclusionMode.bentCone becomes available. The bent normal is geometric (reconstructed from depth), so it does not carry normal-map detail. Only used by AmbientOcclusionMethod.groundTruth when visibilityBitmask is disabled.
Implementation
bool bentNormals = false;
