title: How to feed a transform.position into shader graph?
body: <p>I am trying to mask a sprite by using shader graph.</p>
  <p>Here is a picture of what I have so far:</p>

  <p>my problem is that when I feed the mask texture into the shader it centers itself on the main texture, as you see in this image.</p>
  <p>See the slightly transparent checkerboard to the right side of the character? I only want this operation to affect the parts where the checkerboard intercepts with the character.</p>
  <p>For this I would need someway to displace and scale(?) the mask texture so that it detaches from the center of the main texture.</p>
  <p>What nodes do I have to add to accomplish this, and where to connect them? Thanks.</p>
