tex – Specifies a texture that will be used for rendering the ExtraTex channel.
Consider for Anti-Aliasing – When enabled, anti-aliasing will be used where possible.
The ExtraTex Render Element can be thought of as a container into which render elements can be plugged into. The examples below show two different Render Elements. One shows the UV Coordinates produced by connecting a VRaySamplerInfo node. The other shows an Ambient Occlusion pass created by connecting a VRayDirt node.
The values for both the VRaySamplerInfo node and the VRayDirt node are set within their respective node and not the ExtraTex Render Element. It can be a good workflow practice to ensure each ExtraTex Render Element is named according to the pass it contains. See the VRaySamplerInfo page for more information on what other passes it can produce in this way. See the VRayDirt page for full details of the parameters for it.
