Marty McFly's Ambient Obscurance (MXAO) with IL

With bMXAOPerPixelNormalsEnable enabled

However bMXAOPerPixelNormalsEnable disabled this looks nicer with the text

MXAO Off:

MXAO On:

#define fMXAOAmbientOcclusionAmount 1.15 //[0.0 to 2.0] Linearly increases AO intensity. Can cause pitch black clipping if set too high.
#define bMXAOIndirectLightingEnable 1 //[0 or 1] Enables Indirect Lighting calculation. Will cause a major fps hit.
#define fMXAOIndirectLightingAmount 3.2 //[0.0 to 8.0] Linearly increases IL intensity.
#define fMXAOIndirectLightingSaturation 1.2 //[0.0 to 3.0] Boosts IL saturation for more pronounced effect.

#define fMXAOSampleRadius 6.5 //[0.5 to 20.0] Sample radius of GI, higher values drop performance. Heavily depending on game, GTASA: 10 = GTA V: 40ish
#define iMXAOSampleCount 24 //[16 to 254] Amount of MXAO samples. Higher means more accurate and less noisy AO at the cost of fps.
#define bMXAOSmartSamplingEnable 1 //[0 or 1] Enables smart sample count reduction for far areas. May look ugly when low sample count (16 or less) is used, turn it off then.
#define iMXAOBayerDitherLevel 7 //[2 to 8] 2^ditherlevel: size of AO sampling pattern size. Lower values mean less distinctive sample dirs and haloing.
#define fMXAONormalBias 0.2 //[0.0 to 0.4] Normals bias to reduce self-occlusion of surfaces that have a low angle to each other.
#define bMXAOPerPixelNormalsEnable 1 //[0 or 1] TEST! Enables per pixel normals derived from color input so surfaces get some relief instead of being 100% flat.
#define bMXAOBackfaceCheckEnable 1 //[0 or 1] For indirect lighting only! Enables back face check so surfaces facing away from the source position don't cast light. It comes with a slight fps drop.
#define bMXAOBoundaryCheckEnable 1 //[0 or 1] Enables screen boundary check for samples. Can be useful to remove odd behaviour with too high sample radius / objects very close to camera. It comes with a slight fps drop.
#define bMXAOLowPrecisionEnable 1 //[0 or 1] Enables lower bit mode for AO source texture (R32F vs R16F). This will improve performance but may introduce some artifacts at distant objects.
#define fMXAOBlurSharpness 1.0 //[0.0 to 3.0] AO sharpness, higher means more sharp geometry edges but noisier AO, less means smoother AO but blurry in the distance.
#define fMXAOBlurSteps 2 //[2 to 7] Offset count for AO smoothening. Higher means more smooth AO but also blurrier AO.
#define fMXAOMipLevelIL 2 //[0 to 4] Miplevel of IL texture. 0 = fullscreen, 1 = 1/2 screen width/height, 2 = 1/4 screen width/height and so forth.
#define fMXAOMipLevelAO 0 //[0 to 2] Miplevel of AO texture. 0 = fullscreen, 1 = 1/2 screen width/height, 2 = 1/4 screen width/height and so forth. Best results: IL MipLevel = AO MipLevel + 2

//custom variables, depleted after Framework implementation.
