Per-Camera LOD bias/max LOD

Question

I generally have 2 cameras used in my scene, one for the actual scene rendering and another to render realtime reflections. Is it possible to have a per-camera LOD bias or max LOD so the camera rendering realtime reflections will render less detailed models?

A solution that works for me is to change the global QualitySettings.lodBias in OnPreCull() and setting it back in OnPostRender(). It won't work when changing it in OnPreRender() because it is already too late in the render loop to change there.

 class CustomLodBias : MonoBehaviour
 {
     public float LodBiasFactor = 1F;
     float originalLodBias = 0F;
 
     private void OnPreCull()
     {
         originalLodBias = QualitySettings.lodBias;
         QualitySettings.lodBias = originalLodBias * LodBiasFactor;
     }
 
     private void OnPostRender()
     {
         QualitySettings.lodBias = originalLodBias;
     }
 }

Attach the script to any camera where you want to set a custom lodBias offset.
