The Triplanar map assigns 2D TexturesTextures are used to add details to a surface. Textures can be procedural or imported raster files. on Objects that do not have UV coordinates. This Node works by projecting one or more Textures along either Object or world space X,Y, and Z axes. In the following image (Figure 1), different colored RGB Spectrum maps connect to all six texture position inputs (TexturePosX, TextureNegX, TexturePosY, TextureNegY, TexturePosZ, TextureNegZ) of the Triplanar map node. The result is illustrated in Figure 2.
