Tell me what you think (what could be better) PS. I know about the clipping cells, and I've found the solution, but that was after I rendered it. Any questions? Post them here! I have posted the .blend file below. Use it for anything you want, however you want.
Of course I used Cycles. Rendered with my 7870. However I'm considering about using Luxrender in my next project, because Cycles doesn't support AMD cards completely. I haven't noticed AMD released a new driver, have to see if Cycles works properly now with my graphics. UPDATE: No still same problems...
Only Nvidia cards can use GPU renders right now, due Cuda being a Nvidia feature. I heard that they are working on OpenCL support in Cycles to allow AMD users to use their Gpu too. I can tell you that GPU Renders are about 4 times or more faster than Cpu of ones. How much did it take you to render the whole thing? How many samples?
well it took maybe 20hours in total, 300 frames, 200 samples, 1280x720 100% Also I actually can set to render with my AMD card with Cycles. I just used a trick where you set some variable from 0 to 1. - - - Updated - - - I totally added the .blend file for your use. Do what you want with it!
It seems to me, that the actual cup is breaking too early, as it breaks when it just got through the cup handle... even though i don't know if my feelings about that are actually right, as the bullet has a lot of power...
