triPlanarTextureField

RayTK

v0.40

Texture field that uses surface normals (or other blending techniques) to apply a texture facing each axis.

On a cube centered at the origin, this has the effect of placing the texture on each side of the cube. For a sphere, when using normal blending, the texture for each axis will smoothly blend as the surface normal shifts from one axis to another.

Textures are centered at 0,0 with coordinates ranging from -0.5 to 0.5.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Enable
Return Type	Type of value to produce.
Float: Single float value (from the R channel). Vector: RGBA values.
Translate		Runtime	Baked
Scale		Runtime	Baked
Use Separate Textures	Whether to use a single texture for all axes, or a separate texture for each axis.	Baked	Baked
Texture
Texture X
Texture Y
Texture Z
Extend Mode	How to handle coordinates outside the texture’s bounds.	Semi-Baked	Semi-Baked
Hold: Clamp the coordinates so that the last pixel on each side is extended out infinitely. Zero: Produces values of 0 outside the bounds. Repeat: Tiles the texture. Mirror: Tiles the texture, but flips alternating copies of it.
Blend Mode	How to combine the colors from each axis.	Semi-Baked	Semi-Baked
Normal Blend: Use surface normals to blend the colors. Note that this can cause issues with material local positioning. Add Axes: Add the colors from each axis. Axis Maximum: Maximum for each channel from each axis. Axis Average: Average the colors from each axis.
