Ray Epsilon issue

Hi, in a very large scene (60km) it seems Ray epsilon allows correct rendering of details close to camera OR volumetric in the distance.
Somehow it seems Octane cannot put same attention on very small and very large scale and this is a very important limitation.
Is there a way to force octane to care about everything at maximum quality ?

Here you see how i get banding in distant volumetric OR bad intersection line between water and sand.

I don't think so. Trying to render small details in a 60km scene is really hard due to the single-precision floating math limitations. In these cases rendering two passes to comp them later can be the only real solution.

Hi Paolo, I would try to to downscale the entire scene in Layout. Maybe ?
