Adding Faux Ambient Occlusion to P3D

Recommended Posts

Unfortunately depth map access in P3D is partial meaning the standard AO filters or any other filter that relies on a depth map cannot at present be used.

Probably relates to the engine design given LM haven't added AO as yet, that said it should be possible as I used AO filters in Flight Sim World successfully.

The shader tool used is Reshade and the filter is the AstrayFX\Depth Cues with the No Depth Map option enabled.

Probably best to see the effect by opening each pic in a new tab and then swapping between.

Cheers

?imw=5000&imh=5000&ima=fit&impolicy=Lett

Nice thanks!

Reshade definitely makes a nice improvement on P3D v4.5.

I use the Deband filter to get rid of the awful colour banding in the sky during dawn/dusk/night. Also the Ambient Light filter makes everything much brighter and even works intelligently by increasing it's intensity when the skies are clear and not cloudy.

Does it work in v5.3?

Yes, although I’m not sure either are necessary in 5.3 as the lighting is generally better. Not sure about colour banding. I’ve not used 5+.

Yes it does.

A couple of things to be aware of.

The below entry is needed in the prepar3d.cfg

[USERINTERFACE]

// Set UIHardwareAcceleration from True (the default) to False to enable reshade use.
UIHardwareAcceleration=False

I rename the reshade dll to d3d11.dll to avoid issues, e.g. I use Action! to record which crashes if the dll name is the default of dxgi.dll

You'll need the reshade package that includes addon support, "ReShade_Setup_5.2.2_Addon.exe"

I choose to download all the shader addons when a new reshade version is installed, then cull out those I don't want, shaders end up in ~\Lockheed Martin\Prepar3D v5\reshade-shaders.

And then you set where you want screen grabs to go, frame counter, hotkeys etc.

Have fun 😀

Cheers

There are some fairly wacky shaders in the various packages, tiltshift is interesting one for that miniature model look.

One of the more wacky ones.
