ShaderRequirements

enumeration

Description 描述

Required shader features for some particular shader. Features are bit flags.

Properties 属性



	None		No shader requirements.


	BaseShaders		Indicates that basic shader capability, Shader Model 2.0 level is required.


	Interpolators10		Indicates the shader must have 10 interpolators.


	Interpolators32		Indicates the shader must have 32 interpolators


	MRT4		Indicates the shader must have multiple render targets (at least 4), as in support a fragment shader that can output up to 4 values.


	MRT8		Indicates the shader must have multiple render targets (at least 8), as in support a fragment shader that can output up to 4 values.


	Derivatives		Indicates that derivative (ddx/ddy) instructions support is required in the fragment shader.


	SampleLOD		Indicates the shader requires the support of texture sampling in a fragment shader with an explicit mipmap level.


	FragCoord		Indicates that pixel position (SV_Position) input support is required in the fragment shader.


	Interpolators15Integers		Indicates the shader must have 15 integers and interpolators in total. Unity bundles them together because it is extremely unlikely a GPU/API will ever exist that only has part of that.


	Texture2DArray		Indicates the shader requires 2D array textures.


	Instancing		Indicates the shader must support SV_InstanceID shader input.


	Geometry		Indicates that geometry shader support is required.


	CubeArray		Indicates the shader requires cubemap array support.


	Compute		Indicates that compute shader support is required.


	RandomWrite		Indicates the shader requires have random-write textures (UAVs) support.


	TessellationCompute		Indicates the shader requires the support of tessellation using a compute shader for control points processing. Metal graphics API requires this feature for tessellation.


	TessellationShaders		Indicates the shader requires the support of tessellation using the hull and domain shader stages.


	SparseTexelResident		Indicates the shader requires the support of sparse textures with sampling instructions that return residency information.


	FramebufferFetch		Indicates the shader must support framebuffer fetch, which is the ability to have in+out fragment shader color params.


	MSAATextureSamples		Indicates the shader requires access to MSAA texture samples.
