In the cascaded shadow maps #7064 PR, there were some situations raised that require or would benefit from different cascade configuration to the default which focuses on a perspective camera at head height.

One example was a top-down or isometric type view where a lot of the scene objects are within a small depth range and distributed across the screen with no objects close to the camera. In this case probably fewer or even just one cascade with a higher shadow map resolution could be a better choice.

I think it would be good to try out such situations, tweak the settings, maybe adjust the projection’s near plane as @robtfm suggested in the PR discussion as that impacts the view frustum and if I remember correctly also the cascade projection bounds.
