Right now the primary problem with that example is that the shader defs MAX_CASCADES_PER_LIGHT and MAX_DIRECTIONAL_LIGHTS don't seem to be defined, even though they exist as constants inside of Bevy.

I don't yet understand exactly why that's the case.

error: expected expression, found '#'
    ┌─ wgsl:192:41
    │
192 │     cascades: array<DirectionalCascade, #{MAX_CASCADES_PER_LIGHT}>,
    │                                         ^ expected expression

That turned out to be very quick! The fix was this one: bevyengine/bevy#7375

Greats thanks !!
