Hello does anyone know how i can apply Ambient Occlusion nothing changes when i render its just the same ? It works correctly in the compositor, but after rendering, it doesn’t show up.
Are you sure you have use nodes activated ?

Looks like you’re doing everything right in your screenshot so there must be a small mistake somewhere else…
Composing’s handling method is correct.
Maybe it’s a matter of time to process nodes after rendering, maybe it’s not updating, I’m not sure.

How to speed up the processing of Composing
This is to select GPU processing in Options settings.
There are options on the Composing N panel. -
Problems that are not visible in the rendering window can be seen by selecting the Render Results or Viewer Node entry where you can view the image, such as in the UV window.
