Hi! When plugging the outline into vertex offset it into it only allows me to add one outline even if i add 2 together. is there any way to render and outline behind another so i basically get a double outline around my mesh?
The Outline node creates a separate pass for the effect to work, however, due to a limitation of our implementation of this node, even if you use additional copies of it only one pass will be generated, so it won't be possible to do what you intend through it.
Alternatively, you could set up a multipass shader through our shader templates system in order to implement your own outline method over several passes, as a possible solution.
