title: Drawing on one Whiteboard (Render Target) is copied to all Whiteboards?
body: <p>I'm using the Unreal Engine 4 <a href="https://forums.unrealengine.com/development-discussion/vr-ar-development/83197-vr-content-examples" rel="nofollow noreferrer">VR Content Examples</a> where it has a whiteboard you can draw on. It uses render targets to render the line to the canvas.</p>
  
  <p>The problem is, when I copy the whiteboard to use somewhere else in the level, it shows the same drawing, like this: </p>
  
  <p><a href="https://i.stack.imgur.com/4FhuN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4FhuN.png" alt="duplicate drawing"></a></p>
  
  <p>Here is the material and texture I am using: </p>
  
  <p><a href="https://i.stack.imgur.com/2Jry5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2Jry5.png" alt="material and render target texture"></a></p>
  
  <p>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?</p>
  
  <p>Edit (Additional Details): I made a copy of the original render target and tried specifying that instead, I also made a material instance of the original and specified that for the copy but still the same issue. I tried to dynamically create a render target and material instance as you can see here <a href="https://answers.unrealengine.com/questions/828892/drawing-on-one-whiteboard-render-target-is-copied.html" rel="nofollow noreferrer">https://answers.unrealengine.com/questions/828892/drawing-on-one-whiteboard-render-target-is-copied.html</a> , but then i couldn't draw on it; so I only did it to two of them and it still had the same issue </p>
