Drawing on one Whiteboard (Render Target) is copied to all Whiteboards?
I'm using the Unreal Engine 4 VR Content Examples where it has a whiteboard you can draw on. It uses render targets to render the line to the canvas.
The problem is, when I copy the whiteboard to use somewhere else in the level, it shows the same drawing, like this:
Here is the material and texture I am using:
I tried to make a copy of the material and the texture and use it on one of the whiteboards but it has the same result. I'm not sure why the render target is not instanced/unique? Why is it drawing on the same thing on multiple instances of the whiteboard?

In the construction script you need to "create dynamic material instance" then promote it to a variable. Assign that material instance to the board material and use that instance throughout the blueprint.
