I'd like to know which is the fastest and simple way to create horizon fog.
My scene has a large nurbs plane with a displacement map which rapresents my terrain; my camera is placed more or less in the center of this plane and when I render (I use Mental Ray) I can see the borders ot the plane, and I don't like it, so I'd like to put a sort of horizon fog to hide the borders.
Thank you very much.
P.S. I've tried to use the EnvFog but using an HRDI illumination it seems not work correctly and I've some black areas if I render.
I've red something about render using depthMap and then apply the fog with a compositing Software, but I don't know this workflow.
