// ++++++++++++++++++++++++++++++++++++++++++++++++++++++ // *** PPFX Post-Processing Suite 1.03.29 for ReShade // *** SHADER AUTHOR: Pascal Matthäus ( Euda ) // ++++++++++++++++++++++++++++++++++++++++++++++++++++++ //+++++++++++++++++++++++++++++ // DEV_NOTES //+++++++++++++++++++++++++++++ //+++++++++++++++++++++++++++++ // USED EFFECTS //+++++++++++++++++++++++++++++ #define ENABLE_SSDO 1 // Screen Space Directional Occlusion | Ambient Occlusion simulates diffuse shadows/self-shadowing of geometry. Indirect Lighting brightens objects that are exposed to a certain "light source" you may specify in the parameters below. This approach takes directional information into account and simulates indirect light bounces, approximating global illumination. #define ENABLE_BLOOM 1 // Bloom | This effect lets bright pixels bleed their light into their surroundings. It is fast, highly customizable and fits to many games. I suggest you take a look and play around with the configs. #define ENABLE_GODRAYS 0 // Godrays | Lets bright areas cast rays on the screen. #define ENABLE_TONEMAP 0 // Tonemap | As brightness-increasing effects like bloom will push colors above the maximum brightness of standard displays and thus oversaturate colors and lead to ugly white "patches" in bright areas, the colors have to be "remapped" into the displays range. Several techniques exist for that, actually it's a whole scientific field. Configurable of course. #define ENABLE_UNSHARPMASK 1 // Unsharp Masking | Applies a common technique to sharpen the image. Two versions exist: One is only avaiable if you activated bloom and increases the contrast of "surfaces" (Wikipedia advised, sir.) The second one only sharps edges. #define ENABLE_FILMGRAIN 0 // Filmgrain | Adds temporal noise to the image. May be great if you'd like to simulate old movies or create a certain, distinctive look. Of course nobody likes to play with a bunch of noise overlayed so keep it subtle. #define ENABLE_VIBRANCE 0 // Vibrance | Vibrance is a color saturation control which considers the pixel's original saturation in order to prevent oversaturation and other artifacts. Yields a vivid, well, vibrant look. #define ENABLE_LIFTGAMMAGAIN 0 // LiftGammaGain | This effect adds an individual color filter for three brightness levels (Lift = Shadows, dark tones | Gamma = Midtones | Gain = Lights, bright tones) #define ENABLE_TECHNICOLOR 0 // Technicolor 3-Strip | Simulates the look of old movies produced with the Technicolor Process 4 (3-Strip). This approach is based on the Photoshop "3Strip"-LUT. Stylistically fits some games. #define ENABLE_LENSDIRT 0 // Lensdirt | Simulates a dirty lens. This effect was introduced in Battlefield 3 back in 2011 and since then was used by many further gamestudios. #define ENABLE_LETTERBOX 0 // Letterbox | Adds black bars on top & bottom of the screen. Some people hate it, some say it leads to a "cineastic experience". Try and see for yourself. #define ENABLE_LOGGAMMA 1 // Alternative Gamma-Correction | Abuses a common, detail-preserving alternative for standard Gamma-encoding (sRGB) to achieve a higher contrast. Can look nice on washed-out-looking visuals. //+++++++++++++++++++++++++++++ // CUSTOM PARAMETERS //+++++++++++++++++++++++++++++ // ** SSDO ** #define ssdoIntensity 2.000 // SSDO Intensity - The intensity curve applied to the effect. High values may produce banding when used along with RGBA8 FilterPrecision. As increasing the precision to RGBA16F will heavily affect performance, rather combine Intensity and Amount if you want high visibility | 0.001 - 20.000 #define ssdoAmount 2.000 // SSDO Amount - A multiplier applied to occlusion/lighting factors when they are calculated. High values increase the effect's visibilty but may expose artifacts and noise | 0.001 - 20.000 #define ssdoAOMix 1.000 // SSDO Ambient Occlusion Mix - Ambient occlusion darkens geometry if it is occluded relative to the camera's point of view. This simulates the fact that "blocked" light can't reach geometry behind the blocker. This results in diffuse, blurry shadows. | This value controls the darkening amount | 0.000 - 1.000 #define ssdoILMix 1.000 // SSDO Indirect Lighting Mix - Geometry that is exposed to the static light source (specified below with ssdoLightPos) gets brightened. This value controls the brightening amount | 0.000 - 1.000 #define ssdoBounceMultiplier 0.900 // SSDO Indirect Bounce Color Multiplier - SSDO includes an indirect bounce of light which means that colors of objects may interact with each other. This value controls the effects' visibility | 0.000 - 1.000 #define ssdoBounceSaturation 0.000 // SSDO Indirect Bounce Color Saturation - High values may look strange | 0.000 - 20.000 #define ssdoSampleAmount 16 // SSDO Sample Count - The amount of samples taken to accumulate SSDO. Affects quality, reduces noise and almost linearly affects performance. Current high-end systems should max out at ~32 samples at Full HD to reach desirable framerates | 2 - 250 #define ssdoSampleRange 150.5 // SSDO Sample Range - Maximum 3D-distance (in pixels) for occluders to occlude geometry. High values reduce cache coherence, lead to cache misses and thus decrease performance so keep this below ~150. You may prevent this performance drop by increasing ssdoSourceLOD | 4.000 - 400.000 #define ssdoSamplePrecision RGBA16F // SSDO Sample Precision - The texture format of the source texture used to calculate the effect. RGBA8 is generally too low, RGBA16F should be the sweet-spot. RGBA32F is overkill and heavily kills your FPS. #define ssdoSourceLOD 0 // SSDO Source LOD - The Mipmap-level of the source texture used to calculate the occlusion/indirect light. 0 = full resolution, 1 = half-axis resolution, 2 = quarter-axis resolution etc. Combined with high SampleRange-values, this may improve performance with a slight loss of quality | 0 - 3 #define ssdoBounceLOD 3 // SSDO Source LOD - The Mipmap-level of the color texture used to calculate the light bounces. 0 = full resolution, 1 = half-axis resolution, 2 = quarter-axis resolution etc. Combined with high SampleRange-values, this may improve performance with a slight loss of quality | 0 - 3 #define ssdoLOD 0 // SSDO LOD - The resolution which the effect is calculated in. 0 = full-screen, 1 = half, 2 = quarter, 3 = one-eighth #define ssdoFilterScale 0.8 // SSDO Filter Scale Factor - Resolution control for the filter where noise the technique produces gets removed. Performance-affective. 0.5 means half resolution, 0.25 = quarter res, 1 = full-res. etc. Values above 1.0 yield a downsampled blur which doesn't make sense and is not recommended | 0.1 - 4.0 #define ssdoFilterRadius 12 // SSDO Filter Radius - The blur radius that is used to filter out the noise the technique produces. Don't push this too high, everything between 8 - 24 is recommended (depending from SampleAmount, SampleRange, Intensity and Amount) | 2 - 100 #define ssdoFilterPrecision RGBA16 // SSDO Filter Precision - The texture format used when filtering out the SSDO's noise. Use this to prevent banding artifacts that you may see in combination with very high ssdoIntensity values. RGBA16F, RGBA32F or, standard, RGBA8. Strongly suggest the latter to keep high framerates #define ssdoFilterStep 1 // SSDO Filter Step - A performance optimization for the filter, introducing interleaved sampling. Leave it at 1 and rather use FilterScale to improve the filter performance | 1 - 16 #define ssdoLightPos float3(0.0,0.2,0.8) // SSDO Light Position - The view-space position of the virtual light-source used to calculate occlusion in XYZ-axis'. (0.0,0.0,1.0) means the light is located on the camera. Values should sum 1.0 together. High Z-axis-values recommended. | 0.0 - 1.0 #define ssdoMixMode 1 // SSDO Mix Mode - 1 = Multiply (visually best imo), 2 = Additive (use with very low ssdoAmount & ssdoIntensity), generally not recommended #define ssdoDebugMode 0 // SSDO Debug Mode - 0 = debug-mode off. 1 outputs the filtered SSDO component, 2 shows you the raw, noisy SSDO right after scattering the occlusion/lighting // ** BLOOM ** #define bloomIntensity 0.500 // Bloom Overall-Intensity - The bloom's exposure, I strongly suggest combining this with a tonemap if you choose a high value here | 0.000 - 10.000 #define bloomRadius 64 // Bloom Sample Radius - Maximum distance within pixels affect each other - directly affetcs performance: Combine with bloomDownsampling to increase your effective radius while keeping a high framerate | 2 - 250 #define bloomDownsampling 4 // Bloom Downsampling Factor - Downscales the image before calculating the bloom, thus drastically increasing performance. '1' is fullscreen which doesn't really make sense. I suggest 2-4. High values will cause temporal aliasing | 1 - 16 #define bloomPrecision RGBA8 // Bloom Sampling Precision - Options: RGBA8 (low quality, high performance) / RGBA16 (high quality, slightly slower depending on your system) / RGBA32F (overkill) #define bloomBlendMode 1 // Bloom Blend Mode - Controls how the bloom is mixed with the original frame - (1: Additive (recommended with tonemaps), 2: Lighten (great for night scenes), 3: Cover (for configuring/debugging)) #define bloomThreshold 0.400 // Bloom Threshold - Pixels darker than this value won't cast bloom | 0.000 - 1.000 #define bloomCurve 1.500 // Bloom Curve - The effect's gamma curve - the higher, the more will bloom be damped in dark areas - and vice versa | 0.100 - 4.000 #define bloomSaturation 2.000 // Bloom Saturation - The effect's color saturation. 0 means white, uncolored bloom, 1.500-3.000 yields a vibrant effect while everything above should make your eyes bleed | 0.000 - 10.000 // ** GODRAYS ** #define godraysSampleAmount 64 // Godrays Sample Amount - Effectively the ray's resolution. Low values may look coarse but yield a higher framerate. | 8 - 250 #define godraysSource float2(0.500,0.400) // Godrays Light Source - The vanishing point of the godrays in screen-space. 0.500,0.500 is the middle of your screen. #define godraysExposure 0.100 // Godrays Exposure - Contribution exposure of each single light patch to the final ray. 0.100 should generally be enough. | 0.010 - 1.000 #define godraysFreq 1.200 // Godrays Frequency - Higher values result in a higher density of the single rays. '1.000' leads to rays that'll always cover the whole screen. Balance between falloff, samples and this value. | 1.000 - 10.000 #define godraysThreshold 0.650 // Godrays Threshold - Pixels darker than this value won't cast rays | 0.000 - 1.000 #define godraysFalloff 1.060 // Godrays Falloff - Lets the rays' brightness fade/falloff with their distance from the light source specified in 'godraysSource' | 1.000 - 2.000 // ** TONEMAP ** #define tonemapMode 3 // Tonemap Mode - choose a tonemapping algorithm fitting your personal taste (1: Linear, recommended for really low bloomIntensity-values, 2: Square, 3: Log10-logarithmic + exposure correction) #define tonemapCurve 3.000 // Tonemap Curve - How 'aggressive' bright colors are compressed. High values may darken the shadows and mid-tones while preserving details in bright regions (almost-bright skies, for instance) | 1.000 - 100.000 #define tonemapExposure 1.200 // Tonemap Exposure Adjustment - Every pixel is multiplied by this value before being tonemapped. You can use this as a brightness control or to specify a mid-gray value for tonemapContrast | 0.001 - 10.000 #define tonemapContrast 1.020 // Tonemap Contrast Intensity - Pixels darker than 1 are darkened, pixels above are exposed by this option. Combine with higher (2 - 7) tonemapExposure-values to create get a desirable look. Don't crank this up too far either | 0.100 - 10.000 #define tonemapSaturateBlacks 0.000 // Tonemap Black Saturation - Some tonemapping algorithms may desaturate your shadows - this option corrects this issue. Dont's use too high values, it is purposed to be a subtle correction | 0.010 - 1.000 // ** UNSHARP MASK ** #define unsharpMaskA 1 // Unsharp Mask A - Small Radius, performs best for edge sharpening #define unsharpMaskB 1 // Unsharp Mask B - Radius = bloomRadius - performs best at local contrast enhancement, bloom has to be enabled! #define unsharpMaskAIntensity 0.150 // Unsharp Mask A Sharpening Intensity - the effects' intensity, be careful - I wouldn't push it futher than 0.500 #define unsharpMaskBIntensity 0.150 // Unsharp Mask B Sharpening Intensity - the effects' intensity, be careful - I wouldn't push it futher than 0.500 #define unsharpMaskAMode 1 // Unsharp Mask A Mode - Controls edge detection (1: RGB, 2: Luma) // ** FILMGRAIN ** #define grainAmount 0.001 // Grain Amount - Visibility of the filmgrain on your screen #define grainPower 1.000 // Grain Power - the noise's exposure #define grainFreq 1.000 // Grain Frequency - how fast the noise will change. Zero disables the frequency, thus just showing a grain-texture #define grainSize 0.300 // Grain Scale - the scale of the grain-texture. Too low values will let you see the tiled pattern of the noise. Too high one's are not realistic // ** VIBRANCE ** #define vibranceAmount 0.700 // Vibrance Amount - The effect's intensity | 0.001 - 10.000 #define vibranceCurve 1.500 // Vibrance Curve - The higher this value, the more the saturation increase will be limited to unsaturated patches (pixels) and vice versa. I suggest values around 1.000 - 1.500, combining high values with high vibranceAmounts will not lead to good results | 0.100 - 4.000 // ** LIFTGAMMAGAIN ** #define lggLiftColor float3(0.100,0.450,1.000) // LiftGammaGain Lift Color - Color filter for Shadows (dark tones) in RGB | 0.000 - 1.000 #define lggGammaColor float3(1.000,0.800,0.850) // LiftGammaGain Gamma Color - Color filter for midtones in RGB | 0.000 - 1.000 #define lggGainColor float3(1.000,0.800,0.700) // LiftGammaGain Gain Color - Color filter for Lights (bright tones) in RGB | 0.000 - 1.000 #define lggMultiplier 0.400 // LiftGammaGain Multiplier - the color filters' intensity. | 0.001 - 4.000 // ** TECHNICOLOR 3-STRIP ** #define techniAmount 0.200 // Technicolor Strength - This parameter controls how strong the Technicolor-effect is applied. Too high values will not lead to UB4R-T3CHNiiC0LOR but very strange frames. Keep it between 0.200 and 2.000 | 0.001 - 10.000 #define techniPunch 0.100 // Technicolor Punch - Normally the effect's only visible on high-chroma pixels - this value helps to punch bright&dark pixels to prevent that | Simulates artifacts produced in the course of colour grading/processing methods back in the day. | 0.000 - 2.000 // ** LENSDIRT ** #define lensdirtIntensity 1.000 // Lensdirt Intensity - The dirt texture's maximum intensity #define lensdirtCurve 1.200 // Lensdirt Curve - The curve which the dirt texture's intensity scales with - try higher values to limit visibility solely to bright/almost-white scenes #define lensdirtSmoothmode 1 // Lensdirt Smooth-mode - If enabled, the bloom texture will be used for brightness check, thus scaling the intensity with the local luma instead of the current pixels' one (bloom has to be enabled!) // ** LETTERBOX ** #define letterboxSize 0.020 // Letterbox Size - The vertical range of the letterbox, 0.5 = black screen // ** LOGGAMMA ** #define logGammaValue 2.200 // Gamma Value - Should match your display's gamma value. The international standard used for almost every consumer display device is 2.2. I would not suggest another value | 0.100 - 4.000 /* * +++++++++++++++++++++++++ DOCS +++++++++++++++++++++++++ * -------------------- * __RESHADE__ (version of the injector) * __VENDOR__ (vendor id) * __DEVICE__ (device id) * __RENDERER__ (Direct3D9: 0xD3D9 / Direct3D10: 0xD3D10 / Direct3D11: 0xD3D11 / OpenGL: 0x061) * * __DATE_YEAR__ (current year) * __DATE_MONTH__ (current month) * __DATE_DAY__ (current day in month) * * BUFFER_WIDTH (screen width) * BUFFER_HEIGHT (screen height) * BUFFER_RCP_WIDTH (reciprocal screen width) * BUFFER_RCP_HEIGHT (reciprocal screen height) * texture imageTex < source = "path/to/image.bmp"; > { ... }; * uniform float frametime < source = "frametime"; >; // Time in milliseconds it took for the last frame to complete. * uniform int framecount < source = "framecount"; >; // Total amount of frames since the game started. * uniform float4 date < source = "date"; >; // float4(year, month (1 - 12), day of month (1 - 31), time in seconds) * uniform float timer < source = "timer"; >; // Timer counting time in milliseconds since game start. * uniform float timeleft < source = "timeleft"; >; // Time in milliseconds that is left until the current technique timeout is reached. * uniform float2 pingpong < source = "pingpong"; min = 0; max = 10; step = 1; >; // Counter that counts up and down between min and max using step as increase value.
