In this video I show a relatively easy way to generate depth maps and height maps in LightWave using the built-in fog tools. Consider this an alternative to using the Compositing Buffer export (or Render Buffer Export in earlier versions of LightWave) if that tool is giving you problems. I also show a few of the fog settings, display settings and setting up an Orthographic Camera. http://youtu.be/0ywUGFiVjr4 –dwburman
