I still have some engine code that generates tangents for objects but... why? Computing the normal mapping basis from derivatives in the shader works great. I don't know why I should leave this code lying around.

My Triplanar article shows of another problem with derivative based normal mapping, hard creases appearing on geometry edges:https://medium.com/@bgolus/normal-mapping-for-a-triplanar-shader-10bf39dca05a …
Oh man one of my former co-workers and current co-worker talking graphics, too cool :-) Matt, Ben and I go waaaay back :-)
