Rendered Animations - Varying translucency with frame rate

[MSPBenson]

Dear All,

I am currently exploring and self teaching the uses of the Animation Package in
UG.
I have managed to animate movement of components using mating condition expressions
and varying them as a function of frame rate. This has given me nice photorealistic
rendered animations.
I have seen an animation produced in 3D Studio Max that has components varying from
solid to translucent and back again.
The only way I can imagine this working in UG is by being able to control the material
properties values as expressions and vary these as a function of frame rate as well.
Has anyone found a way to do this?


Regards,
