This page provides information about the Custom Render Element in V-Ray for Unreal.
Through the Custom Render Element, you can use any of the render channels with a different set of adjustments, allowing you a great flexibility over the rendered image.
Enable the Custom Render Element from the Enable option. From the plus button (), add the needed number of render elements.
Select the down-pointing arrow on the right of the Render Channel Type to open a context menu. You can Insert a new Render Channel Type, Delete the current one or Duplicate it.
The drop-down menu opens a list of all V-Ray Render Channels in alphabetical order. Start typing the name of the needed channel to refine the search. Once selected, the Render Channel Type displays the Render Channel and all its settings.
You can clear all of the selections from the top bin button ().
