This page provides information about the UVW Randomizer node in Cinema 4D.


Overview



The UVW Randomizer node allows applying random offset, rotation and scale to texture nodes, assigned to a single object with different Face IDs or different objects.

Note, that the UVW Randomizer's output can only be connected to the Context input of a Bitmap.

Note also that the Randomizer itself has a Context input port. Even though the Randomizer is a Context node, it can have another Context node attached to it. Refer to the Context section of this page for more.


Properties


Random by Polygon Selection – Considers the face IDs (from unique polygon selections) of the object when feeding the data (color or texture) to the material.

Random by Object ID – Considers the Object IDs of the object when feeding the data (color or texture) to the material.

Random by Mesh ElementAssigns random colors based on the object's element (e.g., teapot lid, etc.) IDs.

Random by Instance – Assigns random colors based on the InstanceID (works for Alembic instances and VRayInstancer source objects).

Random by Node Name – Considers the node name when feeding the data to the material.

Stochastic Tiling – Changes the mapping based on the UV tile.


Tile Blend – Edge blending between adjacent tiles when Stochastic Tiling is used.

Seed – Changes the randomization pattern.



Offset Variance



The offset variance controls the position of the map along the U or V axis.


U Range Min/MaxThe min and max range in which the offset of the U axis is applied.

U Steps – Specifies the number of steps in which the variance interval is achieved.

V Range Min/Max The min and max range in which the offset of the V axis is applied.

V Steps – Specifies the number of steps in which the variance interval is achieved.



Rotation Variance



The rotation variance rotates the texture along the U or V axis.


Rotation Range Min/MaxThe min and max range in which the rotation parameters are applied.

Rotation Steps – Specifies the number of steps in which the variance interval is achieved. For example, if UV rotation is set from 0 to 360 with a Step of 5, the texture is rotated at an angle that is a multiple of 72 degrees (e.g. 72, 144, 216..)



Scale Variance


This rollout controls the variance in the scale parameter.


U Scale Range Min/MaxThe min and max range in which the scale parameters are applied to the U axis.

U Scale Steps – Specifies the number of steps in which the variance interval is achieved on the U axis.

V Scale Range Min/MaxThe min and max range in which the scale parameters are applied to the V axis.

V Scale Steps – Specifies the number of steps in which the variance interval is achieved on the U axis.

V Scale Unlocked – When enabled, the U and V axes can be scaled separately.


Mapping


Wrap U/V – Controls how the map is wrapped.

None – It is rendered as is.
Tile – Tiles the bitmap.
Mirror TileTiles the bitmap in a mirror pattern.

 Crop U/V – When enabled, crops the map on respective axis.

Wrap Mode – Specifies how to wrap the map:

On 0.5 Boundary
On Integer Boundary



Context



Context – Allows the attachment of another Context node (UVW generator) to generate a UVW texture, which the Randomizer modifies . If no Context node is connected, or the connected Context node does not generate a UVW map, the Randomizer uses the default UVW generator. For more information, visit the Context Nodes page.
