====== Texture Repetition ======

The Texture Repetition nodes takes an images that is no tileable and randomly splats it onto a surface using a projection.

The random mixing is controlled by an underlying noise function.

This works best for images that are more organic and irregular in nature.

===== Controls =====
{{ :tools:pasted:20210208-121948.png}}

==== Image ====

The pop-up allows for selecting a loaded or loading a new image.
==== Texture Scale ====

This setting defines how far a texture will be shifted.

{{:tools:texturerepetition_texture.png?480|}}
==== Noise Scale ====

This setting changes the scale of the underlying noise used to shift the texture.

{{:tools:texturerepetition_random.png?480|}}
==== Noise Seed ====

An integer number to initialize the random number generator used for the noise. This allows for different distributions even if all other settings stay the same.
==== Pixel Blending / Use MipMaps / MipMap Strength / Bump Strength ====

These correspond to the same controls on the native image nodes.


==== Triplanar Mapping ====
{{ :tools:pasted:20210208-121923.png}}

Triplanar mapping is a type of cubic texture mapping with edge blending.

Please have a look at the [[tools:triplanar_mapper|]] for a more elaborate explanation.

=== Use Triplanar Mapping ===

Activating this toggle enables Triplanar mapping, overring the Projection input and the use of the default UVs. It also enables the controls below used to control the mapping.

Controls not described here work identically to those used by the native 2D Image node.

=== Triplanar Blend ===
This controls how hard/soft the blend of the planar projections is as the normals point away from the major axes.

|{{:tools:triplanar_blending0.png?nolink&200|0% Blend}}|{{:tools:triplanar_blending20.png?nolink&200|20% Blend}}|{{:tools:triplanar_blending50.png?nolink&200|20% Blend}}| {{:tools:triplanar_blending100.png?nolink%200|100% Blend}}|
|0% Blend|20% Blend|50% Blend|100% Blend|

We recommend a value between 5% and 20% for most uses.

=== World/Deformed Coords ===
This controls if the blending is computed in local or in world space. Please note, this only affects how the blending is computed, not how the images are projected.

=== UV Tiles ===
== Flip Reverse Side ==

If this option is enabled, the projected image will be flipped on the U texture coordinate axis on the negative side of the projection. This can be used to make images containing text be readable on the back side of a mesh as well.

=== UV Offset ===

Adds an offset to the computed UV coordinates. This can even be used to animate a texture across a surface.



===== Connections =====
{{ :tools:pasted:20210208-113135.png}}
==== Inputs ====

Most inputs override the corresponding controls on a per spot basis, the exceptions are documented here.

=== Projection ===

This defines the Projection to use. If nothing is connected, the default UV is used.

This input is ignored if triplanar mapping is used.




==== Outputs ====
=== Colour ===

Outputs the colour of the repeated image.

=== Luma ===

Outputs the luminance of the repeated image.

=== Alpha ===

Outputs the alpha of the repeated image.

=== Bump ===

Outputs a bump map computed from the luminance of the repeated image.
