Formula Shader
Basic ShaderFormula Shader
Users who possess a certain level of mathematical skills can use the Formula shader to create gray scale gradients using a formula. The variables are the texture coordinates U, V and W, position coordinates (both local and global) X, Y, Z and T (for time) as well as the User Data created by the user (note: User Data names cannot contain spaces or punctuation!).
When rendering in 32-bit color depth, the Color setting is not restricted to an RGB range of 0 to 255. Very high values can also be applied, which gives the Formula shader a type of HDRI effect.
