>From what I see, AlternateAppearance substitutes entire appearance of affected object. Is there any way to substitute only specific parts of appearance ? I would like object inside scope to become semi-transparent - thus replacing only TransparencyAttributes setting. I would like Material/Texture to stay the same. Is it possible ? I want to make objects close to view semitransparent by adding AlternateAppearance to PlatformGroup. If it is not possible, only other way I can see is messing with collisions and doing it by hand.
