Hi all,
Having some issues with my procedural mesh causing my triplanar shader to make the left/right side of my cube to just show up brown. As shown in the image below it works perfectly on a default unity cube but not my procedural one. The front, back and top face work perfect. The yellow lines are the normals and they are all pointing in the correct direction… im not sure what else could be causing this?

The reason I’m doing it by faces is because my plan is to only generate the faces ill need.

EDIT: Solved. Issue ended up being inside the triplanar shading I was handing normal mapping wrong.
