ShadowInstancedDraw Type
An instanced caster draw collected for the shadow pass.
Instanced geometry (e.g. a game world's block grid rendered via DrawInstanced) MUST
cast shadows. Unlike ShadowMeshDraw this carries many per-instance world transforms;
the pass renders it via the depth effect's DepthInstanced technique with a two-stream
vertex bind (mesh + per-instance VertexInstanceWorld), one DrawInstancedPrimitives
per light. No per-instance frustum cull — the sample already chunk-culls the source commands,
so the emitted count is small; the cost is bounded by the surviving instance counts.

Description
|
Full Usage:
CastsShadow
Field type: bool
|
Whether this draw was emitted while shadows were enabled (see ShadowMeshDraw).
|
The command's per-instance tint colors — read by the instance filter (null when the command drew uncolored; nothing to filter then).
|
|
|
Which instances cast: the transparent tint instances defer to the sorted transparent pass in the forward pipeline, so depth renders the opaque half only.
