Raytrace and Lenses

Maya 2020 fundamentals - modelling the real world

Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

I've modeled a dispersing lens and placed it over a hole in a piece of geometry. I've places a light on one side to create some sort of a flashlight...
Problem is, even though I turned raytracing and raytrace shadows on, and gave the lens a refractive index of 1.5(glass) it doesn't effect the shadows on the other side - I get exactly the same shadows with 1 and 1.5 refractive indexes.

Does someone know what I need to do to get a more realistic raytracing?
Thanks in advance,
Benny

When in doubt, delete history and freeze transformations.

Can global illumination help me with this? I tried turning it on and got some really weird results... If so, can someone please post some tutorials about it?
Thanks in advance,
