it's the part of the ocean, that's far away from the camera, at the horizon, that troubles me. the ocean close the camera works fine, so i don't think its a dicing problem. when i use z-importance, it just flattens the ocean at a certain distance from the camera and i get a straight line between diced geo and undiced geo. doesn't really help for the perspective i am using.

When i render my Houdini Ocean in Mantra PBR, the images always get very noisy towards the horizon. I just use a simple light setup with a Sky-HDRI, no other lights used in the scene. I tried to isolate what is causing the noise, but it seems like the noise is present in almost all the AOVs. I increased pixel samples to 8x8, max Ray Samples to 16, Reflection Quality to 3, i even increased the Sampling Quality in the Environment Light to 8. The Rendering times go up like crazy, to 4 hours max per frame (Res. 1920x1080) but the noisy horizon just doesn't seem to get any better.

Any Tips? Maybe someone else encountered the same problem and found a solution for it. Thanks!
