This page contains information about the V-Ray AOV Bind VOP node. Overview The V-Ray AOV Bind VOP node (V-Ray AovBind) is used to export a V-Ray Extra Texture element based on the attached input. The input texture is applied over the geometry associated with the material holding the AOV bind. Workflow There are different approaches to exporting a V-Ray Extra Texture element through an AOV bind. For more information, see the  V-Ray AOV Bind  tutorial. Download the example files and follow the steps:  Create a box and a sphere in |obj| network. Assign 2 separate materials to them. Assign 2 separate textures to the diffuse color of those materials. Create an AOV Bind VOP for each of those 2 textures. Plug the textures into the AOV Bind  input  socket. Set the  Name  parameter for both AOV Bind nodes to  diffuseMap_box  and  diffuseMap_sphere . Go to the V-Ray Renderer ROP → Images tab → AOV Binds → click the  + Set the  Name 1  parameter to  diffuseMap_box  → this will query every AOV Bind VOP in the scene that shares the same  Name  and put their inputs into a single Extra Texture render element. Do the same for the  diffuseMap_sphere . Render. There are alternative workflows: You could use the Material Output VOP node’s AOV tab → AOVs and plug the texture there. This will automatically generate the AOV with the given  Name1 . You could use an Extra Texture render element with the Referenced Shader VOP to bring in the node that you would have otherwise put into the AOV Bind’s  input  socket. Parameters Name  – Specifies the AOV name.
