Tangent to Surface Normal

• Where to find it:

• Add Adjustment Layer / Extension Pack / Normal Map /

• NodeGraph / Right Mouse Click / Nodes / Filter / Extension Pack / Normal Map /

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.

• Manifold

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.

• Flip Red/Green

Flips the Red/Green Channels of the Normal Map before any computation is done.
