I've got a MAT file that changes the color of the "Fingernails" material. In my MAT file, the instruction goes to "Fingernails". I've applied the MAT to a figure whose nails are named "fingerNails" (note the difference in case placement), and the MAT file doesn't work. Instead it just adds a "Fingernails" element to the drop down list but doesn't actually affect the model. Is there a way to use both versions of fingernail spellings in the MAT file? I tried the idea below but that doesn't work. Any other ideas? a slash instead of a comma? a colon? figure { material Fingernails, fingerNails { KdColor 0.337255 0.133333 0.109804 1 KsColor 0.643137 0.643137 0.643137 1 NsExponent 50.0194 textureMap NO_MAP } } Or should I urge the creator of the figure to rename those (and any other) materials that use a naming convention that's unconventional to names that are conventional? Thanks if anyone has an idea. Dave
