Multiple Object Outlines

I’ve been using the M_Highlight material from the UE content examples project as a bendable to outline objects in a scene. I’m not looking have multiple outlines with different colors visible at the same time but I’ve got no idea how to go about it. I am attaching my current blueprints.

If I have multiple blendables is there a way to apply a different bendable to a different object?

As far as I know this is curently not possible because there is only one custom depth buffer.
Here is an UE forum thread about how this can be done with modifying the engine code:

Ok, thanks for that.
