I make anisotropic reflections using ashikhmin function in PBR. Sample vfl file can be found at odforce.net [forums.odforce.net].
Hope it helps

Hi everybody,
I've created a reflective ring (VEX Metal) and a box below it. Then I generated a caustics map using “Photon Map Generation” rendering engine. When rendering the final image (PBR) using this map there is no caustics reflecting from the ring. But it should be there, right? Can someone tell me what I'm doing wrong, please?
