Hi All,
I seem to be having a bizzare problem with my rendering. When I make a surface reflect and transparent, and then extrude this object (ie making a glass, see the attached render) the inside of the extruded object will go grey and not be transparent.
See the attached render:
try adjusting the ray depth in the materials settings
Iwould would thinks that happening because of the thikness…try what ninjitzue said 
thickness has nothing to do with it. ray depth is how many transparent surfaces a ray will go through before it self-terminates. more like… 1 ray depth for each tansparent/reflective object a ray will come in contact to…
Ok cool I’ll try that.
Apart from that though whatya think of my first render? 
Well I changed the ray depth on the transparancy (for the material) and it still looks the same in the render. I’ll attach the .blend file and upload it when i get home.
looks like an fresnell issue, ill wait for the blend
You know that you can save the render by hitting f3 right?.
Anyone have any ideas? :S
How did you do that? :S
