- If you end up with a black scene upon enabling VXAO, make sure you have a active Skylight in your scene (it helps, if not for initial check if all works only)
- If you want VXAO as your default mode, you have to add the cvar to the engine’ ConsoleVariables.ini located in X:\YourVXGIbuild\Engine\Config folder.
- You can isolate AO only by checking ‘Ambient Occlusion’ as buffer visualization (located in menu where it normally says ‘Lit’
- Works together with SSAO and HBAO+
- Diffuse tracing should still be enabled. Things like VXGI range etc. still matter since your scene will still need to be voxelized.
- Tweak VXAO via the ‘Ambient’ section located between Diffuse and Specular
- Test with setting Diffuse Color to anything but the default black.
Results -if setup properly- should be very good AO.
It’s also much faster than full VXGI.
Hope that helps!
