Tiled (Extended)


  • Where to find it:


    • Add Procedural Layer / Procedural / Extension Pack / Generators


    • NodeGraph / Right Mouse Click / Add Nodes / Procedurals / Extension Pack / Generators





The Tiled Extended Node or Layer can be used to load an Image in the Layerstack or Nodegraph.


It is a combination of an Image Node and a Manifold UV Node.


With all the additional features of the two nodes combined, this node has a lot more features to offer than the

standard Mari 'Tiled' Node and offers similar capabilities when used in the Layerstack as the combined Image/Manifold

Workflow in the Nodegraph


Node Overview



Node 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


  • 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


Image


  • Image

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

to browse for one.


  • 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


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



Tiling Mode
  • Tiling

Determines the tiling mode:




  • Place in UDIM

The UDIM to generate a single image instance in.


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.

Mirror


  • Mirror U

Will mirror your UVs along U (horizontal)


  • Mirror V

Will mirror your UVs along V (vertical)





INTERACTIVE PLACEMENT TAB


Locators


  • Locator Translation Multiplier

UV Modifications are a 2D Process while Locator Movement in the Viewport is a 3D Process.

Moving your Locator a certain distance in the viewport might result in a faster or slower UV move than you are happy with.


The Locator Translation Multiplier is a multiplier against the distance you moved your locator in the viewport allowing you to fine tune

how much the UVs 'stick' to a locator movement.

By default your objects bounding boxes are used as a base for computation of movement.



  • Locator Translation

Allows you to pick or create a Locator for Translation so you can adjust the Manifold Transformations directly in the viewport.

Refer to the Locator Usage Section of the Manifold by Locator Node or the Locator Video above for samples.



Locator Axis Remap


  • X / Y / Z

Determines the mapping of each axis of the locator in the viewport to the node internal coordinate system.


UV Modifications are a 2D Process however the Locator movement in the viewport is a 3D Process.


Your UVs might rotated or your object's faces are aligned in the viewport in a way the default interpretation of a Locator Axis might not

correspond with your actual UVs anymore.


In these cases it might be necessary to change to the Axis mapping in order for Locator Modifications in the Viewport to affect the UVs in a more intuitive way.


  • Invert X / Y / Z

Will invert the selected Axis. This can be useful for example in case of rotated UVs where a viewport locator move upwards moves the uvs downwards.
