Triplanar mapping is an automatic technique of generating texture coordinates. It is particularly useful for landscapes, rocks, trees and other objects with dense, organic patterns.
It is projecting textures from front, top and side, then blending between them.

Individual texture can be chosen for each direction (e.g. snow from the top, rock from the sides).
Usage: just use the Triplanar material. In the node editor, change Scale in mapping nodes and replace texture images.
Thanks for this! Amazing you can do this. How did you figure it out initially?
Awesome. Does anyone know if Blender has a dedicated node for this yet? Also is there a way to group this with a single image input so that you can output to the principled shader without having a massive node tree?
I have been following Star Citizen development and this along with custom normals for bevels and decals is a significant part of how they accomplish amazing visuals.
Cheers.
Awesome. Thank you!
