Syntax

static const uint32 MaxNumParameterCollectionsPerMaterial = 2;

Remarks

Maximum number of parameter collections referenced by a material. Limited to a fairly low count for now, can be raised later. D3D11 allows 15 constant buffers per shader, but many are used by code, and there's state setting overhead to setup each one per material being drawn.
