Name	Type	Default	Meaning
`DeltaSeconds`	`float`	—	Frame time, s: for the stats only; the schedule counts ticks, so it is the same at any frame time.
`RulesMaterial`	`const UMaterialInterface*`	—	The material the active tier draws with; its auto-rule parameters (ReadScatterRulesFromMaterial) decide the layer weights. Null: no auto rules (painted layers only).
