Is there like a default rendering make?

How to create a basic rendering Fog Render like ??

[juanjgon]

Can you send to me this object to test it here? ... it has a weird artifact in the Octane Z-Depth render. Perhaps the model has a problem, or there is a bug in Octane.

I may be on totally wrong path with this but just came to my mind from my experience (and manual) that Octane does not like other than Tris and Quads. I had some very strange results when I had a cylinder that had not been Poled. Try to Triple the object and then try again

If you have LWCad then "Make Quad" or "Make Convex" will fix those problems.
Otherwise, go with what Antti said.

I think that this is not the scene with your problem. Please check it

All my mistakes. Was uploaded again

The problem is the dissolve effect in the object. Dissolve in Octane works with the opacity channel of the materials, so I think that it doesn't have the same behavior than in LW. You are making the object transparent, and the Z buffer has wrong data from the polygons inside the object

Anyway a Z buffer in a transparent object has no sense (this is not the real distance to the object surface), and at least for a fog effect I think that you should disable the dissolve feature. In this pass render all the objects without transparency or dissolve effects.
