Formatting Shader Options

I have an elevation grid with values ranging from -0.3 to 0.5m. I would like to highlight the areas where the value is above 0.2m only. Can I either creater a shader that only highlights these values or can I filter out the areas of the elevation grid that are above 0.2m and then apply a shader to that. Any methods to get what I want would be greatly appreciated.



  • I did just work out one option that works. I created a shader with green for the range -0.3 to 0.2 and red for 0.2 to 0.5. I then set the colour green to be transparent for that layer. It works but it seems like a long winded approach. Is there an easier way?

    Go to Alter Elevation tab in elevation grid layer options and set the min and max of what to show.
