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 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.

 

 

Properties


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

Random by Instance – Assigns random colors based on 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.

Random by Render ID – Assigns random colors based on RenderIDs.

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

Random by Mesh Element –  Assigns random colors based on element (e.g. teapot lid, etc.) IDs of the object.

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
