• Mask Offset U/V

Translation values for the Mask in U and V 

• Layer Cutoff

The Layer Cutoff determines the number of iterations and radius around each cell the node runs through before it stops calculating.

If you are experiencing Seams this might be the reason

To better understand this behavior and to anticipate consider this:

• By default each cell is generated in a grid pattern at a scale of 1.
• Each cell has an internal position of 0.0 for its own coordinate system

If you change the position of a cell from its original position of 0.0/0.0 the Layer Cutoff needs to be increased

for a wider sample radius. So for example 

• adding a Random Position Value of 1.0/1.0 means we need to sample up to 1 additional cell around the original cell.
• We need to increase the Layer Cutoff to at least 2

• adding a Random Position Value of 2.0/2.0 means we need to sample up to 2 additional cell around the original cell.
• We need to increase the Layer Cutoff to at least 3

If you change the scale of a cell from its original scale of 1.0  the Layer Cutoff needs to be increased

for a wider sample radius. So for example 

• Changing the Scale to 2 means we need to sample 1 additional cell around the original cell.
• We need to increase the Layer Cutoff to at least 2

• Changing the Scale to 4 means we need to sample 3 additional cell around the original cell.
• We need to increase the Layer Cutoff to at least 4

• Manifold World Scale

The Manifold World Scale controls the size of the Manifold Coordinates returned by the Pattern Manifold Output Port of the Node.

It only affects this Output Port.

An example of using the Manifold World Scale would be when the node is connected to e.g. an Axis Projection via the Pattern Manifold -> Manifold 3D

connected to drive the look of the Axis Projection by the Pattern Engine Node.

The size of the projection of the Axis Projection in this case would be controlled by the Manifold World Scale of the Pattern Engine Node.

Example of driving an Axis Projection Node via the Pattern Manifold of the Pattern Engine Node.

• Projection Rotate X/Y/Z

Will change the rotation of the Triplanar 'Projection Cube' in space.

This should not be confused with changing UV Rotation which will rotate the projected image on

each side of the projection.

and you see projection stretching as a result of it.

Sample of rotating a projection in 3d space. While this example is using

 an Axis Projection Node the concept is the same for the Texture Scatter Triplanar Node
