I've written a post on Triplanar Mapping, and a few alternative ways to set it up in #UnrealEngine to make it more efficient.

It is great for blending different objects together, learn how to use TAA or biplanar mapping to make it cheaper!

I break down the material functions and more in the post, but I am also sharing the project files outright, so you can get a head start implementing these different techniques in your projects.

I'm not the first to setup triplanar mapping there is a lot on the subject, I'm shouting out my references here:

I love tri-planar mapping, and with the absurd geometric density achievable with nanite, it becomes a really useful tool for kitbashing.

I don't think everything should be triplanar mapped, but used as a layer, potentially masked in some manner, it's extremely powerful.

One of the biggest problems with triplanar mapping typically is repetition, and I don't do anything to address that, but I do think that with nanite geometric detail a lot of those issues are lessened, the geometric shapes help break up the tiling repeating patterns a lot.

Also I provide implementations for biplanar, dithered triplanar and conditional triplanar, but all the screenshots in this thread are 100% the dithered version.

Holds up doesn't it? :D

Now that we are at the end of the thread, I do want to call out one last disclaimer.
