I am unable to get Ambient Occlusion to work with Orthogonal camera in iClone 8, Character Creator 4 and 5.
After I enable it, there is no visual change happening.
Also, the "View AO" option doesn't do anything.
Is this feature not working properly with Orthogonal camera or is it not implemented yet?

I recorded a video of the issue which I described happening in iClone 8.
You can see in the video that AO stops working as soon as I switch the camera mode.
