the pieces are reflecting/refracting the scene around them, nothing else: the other chess pieces, the board, the… um… not too well looking floor, and there is also a blue sky, which you can’t see. I had to make that to have better reflections.
WeWa: Cinema 4D doesn’t do caustics, but its renderer is more than adequate for me for now (especially compared to Blenders’ ). As I said I’ve only used it for a few days, and I haven’t figured out why it doesn’t render the shadows yet (it should). The pinkish stuff is the red fuzzy fabric at the bottom of the pieces, showing through the glass.
harkyman: true, I think it looks more “photoreal” in the literal sense of the word. I’ll try to fix it up, so that the focus is better.
Thanks for the comments, I’m going to try posting a better version soon, especially replacing the floor with something else, I’m still not decided on what, though (anyone have any suggestions?)
