The problem is transparency in general. I havn't been able to make anything even remotly transparent. I created a hollow cube with the back removed. I stuck a bulb and at one point a spotlight inside and set a camera on the other. Now I'm very about about not understanding much to do with textures or shading but I am able to find the shading section along with the transparency section. I've also fiddled with the sliders and check boxes within transparency but nothing seems to actually change anything.
