This page provides a guide to the V-Ray user attributes.


Overview

User attributes can source data from the various areas of the scene and apply these values to the V-Ray shaders using the User Integer, User Scalar, and User Color nodes and textures. User Attributes allow for per-shader modifications. There are a number of predefined attributes that can be selected from the User Attribute dropdown menu of the aforementioned textures. Users can also create custom attributes through User Data. 



Predefined User Attributes


User Color

MoGraph Attributes in this list are applicable only to the MoGraph Cloner object when V-Ray User Color is applied to it. These attributes list the source, from which they gather data to feed into the User Color texture or node.


MoGraph Attributes Cinema 4D Attributes
Color – The color value of the Cloner object. Object Color – The default color of the object. This color can be changed from the project settings.   
Color sRGB – the color of the Cloner object in sRGB color values. Display Color – The Display Color, which is determined in the Basic properties of an object. 
ID Ratio (Color) – The index ratio of the Cloner as a grayscale color value. Layer Color – The color of the layer that the object is placed in.
ID Ratio – The index ratio of the Cloner as a zero to one float value.

Index (Normalized) – The index ratio of the clone as a zero to one float value.

Weight – The MoGraph Weight attribute as a zero to one float value.

Clone Offset – The MoGraph Clone Offset attribute as a zero to one float value. 

Time Offset – The MoGraph Time Offset attribute as a zero to one float value.

Falloff Weight – The MoGraph Falloff Weight attribute as a zero to one float value     

Size – The Cloner's size attribute as a vector value.

UVW – The Cloner's UVW attribute as a vector value.


User Scalar

The MoGraph Attributes in this list apply only to the MoGraph Cloner object when V-Ray User Color is applied to it. Each attribute explains what kind of data it sources and where it sources it from.


MoGraph Attributes


ID Ratio – The ID ratio of the clone as a zero to one float value.

Index – The index ratio of the clone.

Weight – The MoGraph Weight attribute as a zero to one float value.

Clone Offset – The MoGraph Clone Offset attribute as a zero to one float value.

Time Offset – The MoGraph Time Offset attribute as a zero to one float value.

Falloff Weight – The MoGraph Falloff Weight attribute as a zero to one float value

Alternative ID – The clone's Alternative ID as an integer value.


Cinema 4D Attributes


Object ID – Overrides the Node Object ID, if specified.
