EnvironTex Box

picture of MR EnvironTex box

The EnvironTex box takes the TAG output from the soft_color_2D box. It allows you to control how the map will affect the environment shader. This type of shader assumes the entire scene is enclosed in a mapped sphere.

Here's a description of the input buttons for this box:

	TAG   is the map pointer from the Texture Shader.
	ROT   is the rotation about the world Y axis for the map.
	BLEND controls the amount of blending.
	MASK  controls the blending method:
		0 = the texture is always opaque; alpha = 1
		1 = the texture is transparent where its alpha < 1
		2 = the texture is transparent where its intensity < 1
    
The x against the outside of the button means that button cannot accept inputs. It is a constant setting and as such cannot become a procedually set variable. This input also cannot become an argument to the shader for the same reason. You will notice it is greyed out in the Argument Editor.

The output is ENV the EnvTex pointer from the Texture Shader for the soft_env_sphere box.
