## Detailed Description

A TechniqueFilter specifies which techniques are used by the FrameGraph when rendering the entities. TechniqueFilter specifies a list of FilterKey objects and Parameter objects. When TechniqueFilter is present in the FrameGraph, only the techiques matching the keys in list are used for rendering. The parameters in the list can be used to set values for shader parameters. The parameters in TechniqueFilter override parameters in Material, Effect, Technique and RenderPass, but are overridden by parameters in RenderPassFilter.
