Clamp Texture Node

The Clamp Texture requires a texture input and then allows for the texture to be “clamped” with the minimum and maximum slider.

ColorCorrect Texture Node

This node has some basic color correction parameters for the input texture.

Mix and CosineMix Texture Node

The Mix textures are used for mixing two textures together (either linearly or according to a cosine wave). In the example below, a Checks Mix was combined with a GaussianSpectrum using a Cosine Mix Texture and connected to the DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. channel of a Diffuse materialUsed for dull, non-reflecting materials or mesh emitters..

Falloff Texture Node

The fall off map is a texture node typically used to control the blend of two materials depending on the viewing angle of the materials geometry.

• Normal: This is the value/lightness (0 to 1) of the map at straight on viewing angles. When used as an input to a mix materialUsed to mix any two material types. node, the normal is the spectral shade value between material 0 and material 1.
• Grazing: This is the value/lightness (0 to 1) of the map at grazing angles. When used as an input to a mix material node, the grazing is the spectral shade value between material 0 and material 1.
• Falloff Index: The relative amount of the two values (normal and grazing). 0.1 will lead to almost complete coverage by the grazing value regardless of viewing angle, where as 15 will lead to complete coverage by the normal value.

The fall off map can also be used for other things, like the input to the opacity of glass.

Falloff is useful for car shaders (at 90 degrees it should have the desired color and in less somewhat darker, but at the same time a bit more reflective), water shaders (tends to be more reflective to low angles of incidence), fabrics like velvet (tend to become almost white at low angles). It is also useful for some metals to simulate some coating effects.

Invert Texture Node

Invert the input texture.

Multiply Texture Node
