Triplanar

The different outputs of the Triplanar node. Note that the Mask Output doesn't need any input texture;
it is a utility output that shows the resulting blending regions map.

Color Texture

Specifies a path to a color texture to use for the mapping. The corresponding output is outColor.

Float Texture

Specifies a path to a float texture to use for the mapping. The corresponding output is outFloat.

Height Texture

A height texture used for displacement and height-based blending. The corresponding output is outHeight.

Mode

As a convenience, Triplanar also provides the usual planar projection (albeit with all the bells and whistles of the triplanar projection).

Scale

The scale of the mapping. Higher scales will enlarge details.

Height-Based Blending

When a height texture is available, it is possible to perform the blending in a more natural way. The images below show how dramatic the improvements can be.

Softness

Tripplanar works by blending textures together using a special algorithm. When Height-Based Blending is Off, this parameter controls the softness of the blend. When Height-Based Blending is On, it controls the size of the region where blending occurs. Note that softness works in both blending modes (with and without height blending) as shown in the images below.,

Noise Intensity

This is used to increase the amount of noise used to blend between the different regions.  

Noise Scale

Controls the global scale of the noise used to blend between the different regions.

Tile Removal

Enables the use of a special algorithm to remove the repetitiveness seen when a texture is tiled.
