View Full Version : displacement mapping

03-08-2007, 05:58 PM
Do LightWave dissplacement maps (not "bump" maps) only displace the verticies of polygons? I can understand this in the interactive windows but it seems to hold through even to the rendered image.

Traditionally (eg. renderman), I would think I could apply a displacement map to even just a single polygon and see the full resolution of the map acting on that object. It's often used as aa nige gag to add detail.

Am I missing something?

Thanks in advance for your insights.

For displacement it needs to be a subpatch - just to make sure and clarify - and you need to adjust the render subpatch level to something high - 10 or above (sometimes 50 - 100). Or use APS such as per pollygon with a very low setting - well under 10 depending on the object. I even use 1 or 2 at times. (The default is 256.00) You can do this on one Subd polygon.
