Infinity Tiling will apply a texture to the UVs based on a Hexadecimal Grid, with each Cell having a different sample point of the
original texture, hiding any repeating pattern when tiled.

The node will work best with input textures that have a chaotic appearance and does not work well with geometric shapes.

Node Overview

Node Ports

Input Ports

Manifold (UV)

The 'Manifold' connection can be used to feed in a coordinate system to evaluate the Image on.

Possible Nodes to attach to are 'UV' & 'Manifold UV' for example to adjust the tiling of the image

Bake Point Image

The Bake Point Image Port allows you to feed in data from upstream nodes that has been baked via a bake point into the Node.

When the node is evaluated, the Bake Point attached to the Port will be sampled and the UDIM 1001 Image will be transferred into

the Image Attribute of the Node.

This allows you to create patterns and textures via a nodegraph and use them directly inside this node with an element of non-destructivness

Example of using a Nodegraph and a Bake Point to dynamically feed a Pattern Generator Node with Node Inputs

Mask

The Mask allows you to change the opacity of areas of your Image

Image Blur (0-10)

The Image Blur Port allows you to control the blurring of Node's Image via a node stream.

The value range of the fed in Node stream needs to be between 0 and 10.

The Mip Map Blur Setting below the Image Attribute inside of the Node's Properties gets added on top of the fed in value.

Node Properties

MAIN TAB

Base Color

It is possible to define a background color for this node. Transparent areas of the node will be filled with the Background Value/Color

if the Background Opacity is set to 1.0.

If no Image is set in the Image attribute the computation of the Node will default to a lightweight, performance friendly method that only

evaluates the background.

Background Value

Defines the grayscale Background value of the Projection.

The Background Value is multiplied against the Background color, so to only use the Value field, set the Background color to white

Background Color

Defines a Background Color for the Projection. This can help to eliminate semi-transparent areas of your projection, caused by the mesh normals

not being aligned with the projection

The Background Color is multiplied against the Background value, so to only use the Color field, set the Background value to 1.0

Background Opacity

Defines if the Projection is filled by default with the Background Color / Background Value

Drag & Drop an image from the image manager or outside of Mari or use the Browse Button

to browse for one.

Optimize Loading

The optimize loading option tries to determine if an image is assigned to the "Image" Attribute.

If no image is assigned the node will run in a highly optimized mode, skipping most of its attribute computations.

The benefit of this method is that the node can be used inside Materials and Material Templates and it will only have an impact

on performance if an image is assigned to it.

Image assigned but not showing ?

The option is off by default because in some cases the node might incorrectly detect that no image is assigned .. even if one is assigned.
In Material Templates it remains on by default.

if you experience issues where the node does not display an image even if one is assigned, untick the option

Mipmap Blur

Allows you to blur the input image. This feature requires Mari 4.6v2.

Blurring can also be controlled via the Image Blur Port of the Node.

If an input is attached to the Image Blur Port of the Node, the value of the Mipmap Blur slider and the Image Blur Port Input will be added together.

Image Type

If an image is specified as a Normal Map, rotating images recalculates normal vectors for correct lighting results.

Below you can see an example of this. The Material and its normal map was rotated 90 degrees from its original output.

With the Normal Map specified in the Image Type, Mari correctly recalculate the normal map vectors for rotation changes resulting in consistent lighting in viewport & render.
If the Normal Map is treated as a 'Standard Texture', no normal orientation is recalcuated, resulting in incorrect lighting in viewport & render

Infinity Tile

Preserve Histogram

If on, the original contrast ratio of the source image will be restored and applied to the result

Patch Tex Scale

The Area each Sample Point covers within the Source Texture

Seed

Allows you to create randomize the result

Filtering

Filter Image

The Filtering Method used for the loaded Image

Anisotropy

If the Filter Method is set to 'Anisotropic' this will determine the amount of filtering when the image is

viewed at grazing angles

Transform Scale

Repeat UV

A global multiplier on the 'Repeat U' and Repeat V' Sliders

Repeat U

Sets the Repeat along the U coordinate (horizontal) multiplied by the 'Repeat UV'

Repeat V

Sets the Repeat along the V coordinate (vertical) multiplied by the 'Repeat UV'

Transform Rotate

Rotate

Will apply a rotation to the UVs around the centre of them (u = 0.5,v = 0.5)

Transform Translate

Translate U / V

Will translate your UVs along U (horizontal) or V (vertical)

Transform Pivot

The Transform Pivot determines the pivot used for any UV Transformation such as Scaling and Rotating

Pivot U / V

When perUDIMPivot is turned on this determines the location of the Pivot for each UDIM. A value of 0.5/0.5 means that

each UDIM has its Transform Pivot in the centre of the Patch.

This is comparable the Transform Pivot you might be familiar with when applying Layer Transformations in Photoshop.

This setting is not evaluated when PerUDIM Pivot is turned off.

Per UDIM Pivot

Affects the transformation pivot for UV Transforms.

With PerUDIMPivot on,all transformation will be performed with a pivot inside each UDIM (as determined by the Pivot U/V Position).

With PerUDIMPivot off, transformations for all UDIMs share one common pivot at the base of UDIM 1001

This will ensure seamless textures across UDIMs when your UV Shell is scaled up and covering multiple UDIMs.

without a cut inbetween.

Transform Mirror

Mirror U

Will mirror your UVs along U (horizontal)

Mirror V

Will mirror your UVs along V (vertical)
