I am pretty sure it's possible, just can't quite figure out how.

I am trying to apply a material to a mesh where I want it to appear if one end is completely opaque, and the other end completely invisible. In other words the mesh (something like a long tube) needs to go from a normal material to literally nothing.

So far I suspect that is has something to do with the transparency or translucency slots of the material's Maps section. Doesn't quite work - yet!

Any pointers? I work with Max 5, and Raytrace mats.

Thanks...

I'd go with applying a ramp to the transparency slot, making sure there's no refractions being calculated.

Thanks - messing with that right now...

Okay - have some results, but I get the two ends that are now translucent, and the middle opaque - as if the effect mirrors itself in the centre. What to change to have it run only from one end to the next?

Thanks... help hugely appreciated.

Either the UVW unwrap or some tile settings for the ramp.

Have been using UVW unwrap anyway.
Screenies attached of settings...
