Thanks for all the tips and ideas,Patrick I look forward to your process . Kixum, I like the fact the light rays are straight in your image. When I get back to doing this , I will definitely look at these ideas. On another note , the final image is going to be very large, the smallest dimension is supposed to be something like 2600 pixels. So this is going to make for a very big image , so come render time for the light cone, is there a way to render just the light cone effect to make things go quicker, then composite the light cone layer and the background scene together.
