internal noise.

(e.g. wood grain or brushed metal)

The Pattern Crop options allow to 'cut' the edges of a patterns or input images, allowing even more variation

• Rotation Pivot Centered

If on, rotation is evaluated against the center position (0.5 / 0.5) of the UVs. 

If a 2D Node is used (as opposed to a triplanar node), this will mean a unique rotation pivot in the center of each udim.

• 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

• Attenuation

Attenuation lowers the value of layers in the background successively for each Layer ID until it reaches a value of 0

• Fill Background

If ticked on, the Pattern will be generated over the Background defined in the Background Color or the background attached to the Background Node port

• Background Color

• Opacity

Set the Opacity for each cell

• Opacity Map Intensity

Determines the influence of the Opacity Map if one is attached to the Opacity Node Port

The Triplanar Settings control the projection of the texture in 3d space.

The settings are similar to a regular Triplanar Node found in Mari.

• 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.

Projection Rotate is useful if your asset is not perfectly aligned in the main world space axis X Y and Z

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

• Edge Falloff Start

The Edge Falloff Start determines the minimum angle where the projection

starts to be fully opaque

• Edge Falloff End

The Edge Falloff End determines the maximum angle where the projection

starts to be fully transparent

• Edge Falloff

The Edge Falloff Curve determines the general Falloff of each projection axis to its sides.

This is similar to adjusting the Edge Falloff Start and Edge Falloff End Sliders however

it allows you to create non-linear edge blending

• Jitter Intensity

Jitter will make the edges of projections less uniform/straight.

The Jitter Intensity determines the amplitude of the the Jitter.

You can overwrite the Noise used for jittering the edges by mapping the Jitter Noise Port in the Nodegraph
