The picture below should sum up what my problem is. For one thing: why is there a solid shadow on a transparent material tube? (double sided). Basically. How do I make the entire thing a nice clear glass tube. I tried settings found on blender wiki amongst other things and am entirely at a loss (the tube is supposed to be broken).
I have one Spot light using Blender engine. Should I not have this?
As you can see, I’ve made some progress - but it now looks like plastic, and the edges of the broken glass are not defined. I added the depth value, but it adds nothing. By depth, do you mean Ray Mirror or Ray Transp?
