Render the nigt scene at diffuse 4 stop at 14000 samples

The problem with black ceilings in AO mode is caused of a wrong AO distance setting (too high). My advice is switch the visor to occlusion mode and adjust the distance until all that excess of occlusion disappears. Its not a drawback al all, but a wrong setup of the render.

After some experimenting, I´ve found that you were right. You can´t have indirectly lit areas in AO mode without some good environment. That means it´s only suitable for daylight scenes. Switching to diffuse solves the problem as you add the bounces calculation.

An interesting point is that for my scene, which is more or less like yours, but very basic and boxy, pathtracing performs faster than diffuse DL. Is there some rule or tip where a more dense rendering kernel can be faster than a supossed another lighter and faster, like in my scene, where PT cleans the noise quicker than diffuse? (it should be slower, in theory)

I've got Octane from the start of development.
But only recently I started to use, and I like it a lot.
Still haven't done that many in Octane yet.

Btw I've done a little post pro on your daylight scene.
I think you should keep the verticals vertical.
The walls are to yellow, they should ideally be white.
The middle wall is blown out.
You forgot to add a 'base' (plint) in the middle wall.
To me the shadows are to dark, especially under the bed (unless you don't want to show us the monster who live there ).
The ceiling looks weird to me.
Anyways these are my opinions, for the rest I like the scene alot.

How do you keep vertical to be vertical? This is possible in vray camera by just clicking a button but how to do it in Octane? Is there a button?

Best wishes for everybody on this forum, and keep developing Octane render


Hi Remon,

I wil give it a new try but what do you mean bij vertical keep to be vertical !!!

First of all best wishes to you and everyone on this forum.

What I mean is, keep the verticals straight.

Make sure the position and target of 'Y' are the same.
If you want the camera to look up or down use the 'Y' in the 'lensShift.'
