    Is there a possibility that we can write our own custom render pipeline that supports shadow cascades on mobile?
    My game has a large open space and 2 cascades can make the resolution good enough for me.
    Without a cascade I have to cut the visible area to like 100 meters to make the shadow resolution good enough for close objects like the player itself or the npc enemies.

    Yes it's possible to write an custom RP that supports cascades. This involves around the use of ShadowSplitData. It's probably easiest to look at how URP uses this info to figure out how to render cascades.

    Would be great if you opensourced what happens inside ComputeDirectionalShadowMatricesAndCullingPrimitives
