I am sure JTK knows about Triplanar texture mapping. It is to solve terrain texture mapping issues like this:

Describe the solution you'd like
I know performance will be impacted as you have to draw 3+ times, but you can include a toggle in the editor/runtime so you can turn it off or on.

Thanks for adding this. I do have some code shelved to add triplanar mapping to mundus already but I need to return to it and finish it.

Definitely can be expensive with the additonal texture lookups but it's worth it in my opinion.

Especially if the terrain texture also has normal textures, then both get sampled multiple times.
