Id like to use grey scale images as texture maps and color them with RGB Luma Tint in order to save disk space. This works with materials that are mono or duo chromatic. The problem is that full transparency cannot be achieved (by me at least) with RGB luma tint. The areas that are designated as fully transparent by the opacity map have a color cast like celophane. I dont think Im making a mistake with the opacity map because the same material works fine with RGB tint or with no tint. Ideas? Thanks.

It sounds like your transparent object may be catching a highlight. Either make it matte or use a shininess map (that matches your opacity map) to eliminate the highlight. – Phil

Thanks to you and Phil for the suggestions. Changing the 3DS.set file did the trick.
