This page provides information on the UVW Randomizer Map.

 

Overview

The VRayUVWRandomizer map allows applying random offset, rotation and scale to textures, assigned to single object with different FaceIDs or different objects. It can be used as a mapping source for VRayHDRI texture nodes only.

Basic Parameters

 

 

Seed – Allows the user to change the randomization pattern.

Randomize – Specifies the meaning of the ID parameters.

By name – Generates a color index based on the name of the node that the texture is applied to. This allows the color to remain consistent if the object is merged into another scene, or X-Ref'd etc.
By element – Assigns random colors based on element (e.g. teapot lid, etc.) IDs of the object.
By face ID – Consider the face IDs of the object when feeding the data (color or texture) to the material.
By instance ID – Assign random colors based on InstanceID (works for Alembic instances and VRayInstancer source objects ).
By particle ID – Assign random colors based on ParticleID (works for VRayInstancer source objects and Thinking Particles).
By render ID –  Assign random colors based on RenderIDs
By object ID – Consider the Object IDs of the object when feeding the data (color or texture) to the material.
By node handle – Each node in 3ds Max is assigned a unique number (a handle) when it is created. This option generates the color index based on that node ID. It is useful because the node handle survives through scene editing - f.e. if you add/remove other objects, or rename them, you will still get the same colors.

Variance – The min and max range in which the scale, offset and rotation parameters are applied

Step – Specifies the interval of repetition of the parameter. For example, if the Step of the UV rotation is set to 5, the texture will be rotated along the U or V axis every 5 degrees.

U/V offset – Controls the position of the texture along the U or V axis.

UV rotation – Rotates the texture along the U or V axis.

U/V scale – Scales the texture along the U or V axis.

 

Coordinates

 

 

These parameters are the regular 3ds Max coordinates parameters as found in the general 3ds Max textures.

 

Noise

 

 

These parameters are the regular 3ds Max noise parameters as found in the general 3ds Max textures.
