Detailed Description

A QTechniqueFilter specifies which techniques are used by the FrameGraph when rendering the entities. QTechniqueFilter specifies a list of QFilterKey objects and QParameter objects. When QTechniqueFilter is present in the FrameGraph, only the techiques matching the keys in the list are used for rendering. The parameters in the list can be used to set values for shader parameters. The parameters in QTechniqueFilter are overridden by parameters in QTechnique and QRenderPass .
