Creates a black and white image, which can be used as a metalness mask when creating PBR shaders.

Object ID

vrayRE_Object_IDReturns solid un-shaded colors to represent a numerical identifiers set through that object's Attributes, Object Property, or assigned material. Useful for selection masks. EXRs and .vrimg formats store as integer values.
Object SelectvrayRE_Object_select16bit/32bitRenders only the object(s) called out with a specific Object or Material ID. This effect is reversible to create a render element that excludes a particular object or objects according to Object or Material ID.
