Consistent AO depending on scene scale

[MajorMeerkatThe3rd]

Hello, I'm having an issue setting up the AO (both HBAO and SSAO) with varying scene sizes.

In this first example, I have a pretty standard setup with the HBAO effect. Everything works as expected.

When I now introduce a scalingFactor that scales all elements in the scene as in this second example, the results of the AO are not consistent. I tried to adjust the distance, thickness and radius by the scalingFactor with no success.

Is there a way to achieve consistent AO results depending on the scene scale?
