I'm working on a fountain, and after doing a few try-out renderings I came to a problem that never happened to me before. I'm not even sure how to explain it, so I'm just going to let the picture do the talking.
If anybody has any idea what is causing such behavior and has any tips, I will greatly appreciate it.
Final notes: I use AC 11. The elements were created from straight lines and arcs (not splines and magic wand). The water material is just a masked image, with plain transparency.
