It’s Boolean, just ‘false’ (0) or ‘true’ (1). With ambient occlusion mode ‘true’, there is no diffuse or specular indirect lighting, but there is ambient lighting with its intensity controlled by r.VXGI.AmbientOcclusionScale.

The standard AO solutions (including UE4’s SSAO) should still be supported with our VXGI integration.
The SSAO is applied to the UE base lighting, and to our VXGI Diffuse term before adding it to the scene color buffer:
SceneColor = ScreenSpaceData.AmbientOcclusion float4(GBuffer.DiffuseColor x ScreenSpaceData.VxgiDiffuse, 0);

To see VXGI’s ‘Voxel AO’, try typing “r.VXGI.AmbientOcclusionMode 1” in the console

and then “r.VXGI.AmbientOcclusionScale XX” to scale the AO output by XX if needed; will do AO-only rendering which can be useful to fine-tune opacity voxelization.

Thanks it works: increasing the scale gets you brighter shades and vice-versa.

Hi,

I’ve pushed a new branch, HBAO+. I took these screenshots from a lighting demo level I downloaded in the marketplace. These pictures show HBAO+ enabled/disabled. There’s nothing special required to use HBAO+ with your existing levels in branch, just type “r.HBAO.Enable 1” at the console.

Thank you for that branch, HBAO+ is among the best (if not the best) AO techniques. still worries me more about the utility and the efficiency of VXGI:if you need to enable SSR and HBAO+ to get reflections and AO with it, while I thought VXGI is able to generate dynamic direct and indirect diffuse/specular and AO according to the movements of the light source(when you the light source moves, of course every resulting effect I mentionned of it changes to some extent according to the lightsource position), without needing any extra hellp from post-process solutions like SSR or HBAO+ (at leats from what your videos tried to make us believe).

Anyway, if is the case, I really hope you create a branch including all game works together so we can enjoy both VXGI and HBAO+ at the same time. Thanks!

I also hope you collaborate with Epic to integrate IBL (Image Based Lighting) in UE4 coupled with VXGI to get the best results with PBR just like Mizuchi engine: watch?v=sYX9I3ONHc4

PS: anyone could help how to disable the normal AO (SSAO), in any scene in general so I can enable HABO+? Thanks !
