r.Mobile.Shadow.CSMShaderCullingMethod

Method to determine which primitives will receive CSM shaders: 0 - disabled (all primitives will receive CSM) 1 - Light frustum, all primitives whose bounding box is within CSM receiving distance. (default) 2 - Combined caster bounds, all primitives whose bounds are within CSM receiving distance and the capsule of the combined bounds of all casters. 3 - Light frustum + caster bounds, all primitives whose bounds are within CSM receiving distance and capsule of at least one caster. (slowest) 4 - Cull all. Prevent primitives from receiving CSM shadows. 5 - Disable culling if mobile distance field shadowing is used for all views. Combine with 16 to change primitive bounding test to spheres instead of box. (i.e. 18 == combined casters + sphere test)
