Using Max 4.2

I'm tyring to use the Lens Effect, Glow but I can't seem to find a way to constrict the glow to a map. I only want certain parts of an object to glow, and I'd like to use a map just like a bump map.

Any help?

Ok, i had the same problem three years ago, in max3, when I tried to make the glow around the continents of my globe ....
The only way i found was to duplicate the globe sphere, first was the oceans and second was the continents with alpha mask (and apllied glow), then mixed everything in vpost, or after effects.
Hope I helped you
cheers ;)

You could use the material effects channel, and then check to use it at the glow effect

had same problem sice max4 tried everitying on earth but can't find solution actually i'm trying with the voice alpha in the glow effect setup with a texture that has alpha channel (i'm not sure what the voice alpha is for)...i think the selective glow doesnt' work even with a opacity map on the material because i think that the glow is applied on the material not on the map...
