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.

Node Overview

Node Ports

The 'Manifold' connection can be used to feed in a coordinate system for the evaluation of the gradient.

Possible node connections are for example the 'Manifold 3D', 'Manifold UV', 'UV', 'Position' etc.

Node Properties
