ProjectTriplanarMap_v2

Overview

ProjectTriplanarMap_v2 uses the normals and position on a mesh to read textures procedurally.

The triplanar projection is a virtual cube, where textures repeat along each cube face. The blending weight for each face’s texture is determined by the face’s alignment with the mesh normal. The transition_width parameter increases or decreases the amount of blending across faces.

The number_of_textures option also determines how the projection works:

one texture means it’s the same on all faces
three textures means the X, Y, Z planes can each have their own texture
six textures means positive and negative X, Y, Z can have unique textures
