Members

	Member name	Description
	Disable	Disables output from the texture stage and all stages with a higher index. To disable texture mapping, set this flag as the color operation for the first texture stage (stage 0). Alpha operations cannot be disabled when color operations are enabled. Setting the alpha operation to Disable when color blending is enabled causes undefined behavior.
	SelectArg1	Uses this texture stage's first color or alpha argument, unmodified, as the output. This operation affects the color and alpha arguments used with the ColorOperation and AlphaOperation properties of a TextureStateManager, respectively. S RGBA = Arg1
	SelectArg2	Uses this texture stage's second color or alpha argument, unmodified, as the output. This operation affects the color and alpha arguments used with the ColorOperation and AlphaOperation properties of a TextureStateManager, respectively. S RGBA = Arg2
	Modulate	Multiplies the components of the arguments. S RGBA = Arg1 * Arg2
	Modulate2X	Multiplies the components of the arguments, then shifts the products 1 bit to the left (effectively multiplying them by 2) for brightening. S RGBA = (Arg1 * Arg2) << 1
	Modulate4X	Multiplies the components of the arguments, then shifts the products 2 bits to the left (effectively multiplying them by 4) for brightening. S RGBA = (Arg1 * Arg2) << 2
	Add	Adds the components of the second argument to the first argument. S RGBA = Arg1 + Arg2
	AddSigned	Adds the components of the arguments with a -0.5 bias, making the effective range of values -0.5 through 0.5. S RGBA = Arg1 + Arg2 -0.5
	AddSigned2X	Adds the components of the arguments with a -0.5 bias and shifts the products 1 bit to the left. S RGBA = (Arg1 + Arg2 -0.5) << 1
	Subtract	Subtracts the components of the second argument from those of the first argument. S RGBA = Arg1 - Arg2
	AddSmooth	Adds the first and second arguments, then subtracts their product from the sum. S RGBA = Arg1 + Arg2 - Arg1 * Arg2
	BlendDiffuseAlpha	Performs linear blending on the current texture stage, using the interpolated alpha from each vertex. S RGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha)
	BlendTextureAlpha	Performs linear blending on the current texture stage, using the interpolated alpha from each vertex. S RGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha)
	BlendFactorAlpha	Performs linear blending on the current texture stage, using a scalar alpha set with the TextureFactor property for a RenderStateManager. S RGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha)
	BlendTextureAlphaPM	Performs linear blending on the current texture stage that uses a premultiplied alpha. S RGBA = Arg1 + Arg2 * (1 - Alpha)
	BlendCurrentAlpha	Performs linear blending on the current texture stage, using the alpha taken from the previous texture stage. S RGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha)
	PreModulate	This flag is set in stage n, the output of which is arg1. If stage n + 1 contains a texture, then the Current value of a TextureArgument is premultiplied by that texture.
	ModulateAlphaAddColor	Modulates the color of the second argument using the alpha of the first argument, then adds the result to argument one. This operation is supported only by using the ColorOperation property of a TextureStateManager. S RGBA = Arg1 RGB + Arg1 A * Arg2 RGB
	ModulateColorAddAlpha	Modulates the arguments, then adds the alpha of the first argument. This operation is supported only by using the ColorOperation property of a TextureStateManager. S RGBA = Arg1 RGB * Arg2 RGB + Arg1 A
	ModulateInvAlphaAddColor	Similar to ModulateAlphaAddColor, but uses the inverse of the alpha of the first argument. This operation is supported only by using the ColorOperation property of a TextureStateManager. S RGBA = (1 - Arg1 A ) * Arg2 RGB + Arg1 RGB
	ModulateInvColorAddAlpha	Similar to ModulateColorAddAlpha, but uses the inverse of the color of the first argument. This operation is supported only by using the ColorOperation property of a TextureStateManager. S RGBA = (1 - Arg1 RGB ) * Arg2 RGB + Arg1 A
	DotProduct3	Modulates the components of each argument as signed components, adds their products, and replicates the sum to all color channels, including alpha. This operation is supported for color and alpha operations. S RGBA = (Arg1 R * Arg2 R + Arg1 G * Arg2 G + Arg1 B * Arg2 B )
	MultiplyAdd	Performs a multiply-accumulate operation, in which this field multiplies the last two arguments, adds them to the remaining input/source argument, and places that into the result. S RGBA = Arg1 + Arg2 *Arg3
	Lerp	Performs linear interpolation between the second and third source arguments by a proportion specified in the first source argument. S RGBA = (Arg1) * Arg2 + (1 - Arg1) * Arg3.
