 This is the Displacement tab of the [[Simple Shape Shader]].
 TG3 introduces some new displacement options, '''Displace relative to surface''' and  '''Displace relative to shader position'''. They allow you to change the way the shader applies displacement. The two images below show the two different methods. The one on the left uses '''Displace relative to surface''' and the other one uses '''Displace relative to shader position'''. Those were the only parameters which changed between the two images.
-'''Displace relative to surface''' is how displacement was always applied in TG2. What happens is that the shader looks at the position of the surface underneath and then applies displacement to that. That means if the surface is lumpy that lumpiness flows through into the shape created by the shader. In this case the shader was making a pyramid and the pyramid shape has been distorted by the underlying terrain.
+<center>
 '''Displace relative to shader position''' ignores the underlying surface and always displaces from the shader position. Currently this means that displacement is applied relative to the Y coordinate of the shader position. As you can see from the image on the right this means that the displaced shape is generated exactly by the shader and not distorted. In this case the shader Y position is 10. You can see there is a "wall" around the bottom of the shape. This accounts for the difference between the edge of the shader (at 10m) and the underlying terrain, which is lower than along 10m along the two edges we can see.

 * '''Displacement edge width:''' This param lets you set the width of the edge area of the shape. To show the edge profile the '''Displacement edge profile''' popup needs to set to something other than "None".
