I used Displacement Exporter to create the grey-scale map used for the heightfield in this POV-Ray image. After drawing some stuff with the spray stroke on the canvas and flattening the tops with a cube using ZCut, I captured the canvas as an alpha and exported the alpha using Displacement Exporter.
Since I couldn’t export 16-bit or 32-bit grayscale images before from ZBrush (only 8-bit grayscale) I always got a stair-stepping effect with heightfields in POV-Ray previously that I couldn’t get rid of.
