Hi Blendermania Family,

I’struggeling with my AO settings and maybe someone have the right clue what is going wrong.
If You have a look at my RenderView You can see AO is fine at the stone rows.

I applied the scale from the object “Stein.001” and recalcuted the normals as well.
Blender v3.6.22, Cycles render engine, no compositing.

Thanks for help

Could you share your .blend so I can check it. Also have you tried baking the AO map?

Hi Alex,

I have to shrink the project before uploading because of my slow upload connection.
Baking is one of the things I’m not familiar with.

Crasy ! - found out the problem.

Starting with making AO visible in the rendered image. Made a copy of the stone row and moved it from 1 to 2. Because the row 2 was visible there have to be something unvisible there.

There was a volume object visible in the rendered image only.

After deleting this object AO was fine.

So volume objects are preventing Anbient Occluien to render.
Is there a solution to use both ?

Glad you figured it out. I am guessing the volume is blocking out the lighting and shadows which basically makes the AO not take effect. Like I mentioned above, I would bake the AO to a texture so that it no longer needs the actual lighting in the scene. This should help:
