Depth Buffer for RE4 not working

I want to use RTGI for RE4 using the latest version of Reshade but I can't seem to get it to recognize the depth buffer. The thing that's confusing is if I enable the DisplayDepth shader I see this under Normal Map (that sure looks like a depth map to me).



But when I try to view the depth map using either DisplayDepth or Debug View in RTGI it get a blank screen. What's the difference between a Normal Map and Depth Map? I've tried every variation of settings in Reshade trying to the depth buffer to show something. What am I missing? In-game AA is disabled BTW.

The normal data is calculated based off depth, so depth buffer access is working fine. You'll need to change the linearization settings to get it to show up as you expect (RESHADE_DEPTH_INPUT_IS_REVERSED and friends). IIRC in RE4 the far plane had to be adjusted a lot (RESHADE_DEPTH_LINEARIZATION_FAR_PLANE).

Thank you, crosire! Now THAT'S more like it! I guess I got confused because whenever the depth channel has been reversed in the past it looked reversed on screen instead of showing nothing at all. All I did was change RESHADE_DEPTH_INPUT_IS_REVERSED=1 to 0 in the ReShade.ini file and viola.

That fixed the depth buffer issue but now I can't get SMAA to work like it did before. Did the reversed depth buffer affect how it handles AA?

Nevermind. I found a better AA shader.
