@DeathMetalDesk: as Wim says. You can do anything, the surface element at the spot is just displaced (in a direction dictated by the surface normal) by any value that comes out of your node tree, multiplied by the displacement value. Do note however, that this displacement value is measured in your local Poser units. So when you're using inches (like BB does), 1.0 means 1" while when using meters (like I do), 1.0 means 1 meter. This must be taken into consideration when implementing node-tree setups from other users.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
