For example, the Red to scalar node will output the red value of the input colour.\n\n\n{|\n|-\n|[[File:RGB2Scalar_01_PaintedShader_Pop.jpg|none|800px|In this example, the Red/Green/Blue to scalar nodes are used to create masks based on a painted shader.

When unchecked the values assigned to its Main Input, if any, are passed through, otherwise a value of 0 is passed through.\n\n \n==Fun with Red to Scalar==\nIn the example below, a simple image is used to define areas for population of crops and irrigation canals.  By extracting the colour channels via the Red/Green/Blue to scalar nodes, and then combining them with other function nodes, like Add scalar and Subtract scalar, mattes can be derived to help control population density or shader influence.\n{|\n|-\n| [[File:RGB2Scalar_03_ImageChannels.jpg|none|800px|The source image and red, green, and blue channels used to extract mattes for the agricultural and irrigation areas in the render below.]]\n|-\n| [[File:RGB2Scalar_04_Render.jpg|none|800px|Render using Red/Green/Blue to scalar nodes to extract mattes from an image to be used for populations of agriculture plants and surface shader for irrigation water.]]\n|-\n| [[File:RGB2Scalar_05_Render_NodeNetwork.jpg|none|800px|Node network view showing use of Red/Green/Blue to scalar nodes to extract mattes from an image to be used for populations of agriculture plants and surface shader for irrigation water.]]\n\n\n<br /n>\n\n\n[[Category:Convert]]"

Basically it modifies the shading state variable for the surface normal before calling the shaders, so that they think they are displacing a surface with a different normal. Any shader that displaces along the normal will then displace along these directions. Displacement in the negative X,Y,Z directions is accomplished if the displacement shader displaces negatively (e.g. if it indents a surface rather than raising it).\n \n'''Settings:'''\n\n\n*'''Name:''' This setting allows you to apply a descriptive name to the node, which can be helpful when using multiple Redirect shader nodes in a project. \n\n\n*'''Enable:''' When checked, the node is active and the settings below will affect the surface.
