Tangent to Surface Normal by Jens Kafitz
The Tangent to Surface Normal Adjustment Node allows you to convert your Tangent Space Normal Map into a surface Normal that
many Mari default nodes can use (Triplanar etc.) in their Calculation, when attached to their 'Normal' Handle in the Nodegraph.
It provides a way to make Mari aware of fine details and surface normals from highres models, when working with lower res geo.
On the left the normals generated with a 'Surface Normal' Node on a lowpoly model.
On the right the normals generated with the 'Tangent to Surface Normal' Adjustment over a Normal Map.
Flips the Red/Green Channels of the Normal Map before any computation is done.
