Create a light file to aid visualization. It should create shadows from several directions. Here's an example:

For 2000i or later: 3Lights.zip (1.0 K)

You can load a light file with a mapkey:

mapkey.lgh.txt (0.7 K)

NOTE: This mapkey uses $HOME. If not defined on your system, edit for absolute path.

UPDATE - July 13, 2001
Sorry if you had trouble with the lights file. It should work better as a .zip
