; SSAO/SSDO config file.
; SSDO is intended to be a full replacement of XWA's shading system. I suggest that
; you actually disable XWA's diffuse shading by going to:
; Menu (press Esc) -> Single Player Video Options, and then set:
; Local Light Source = Off,
; Diffuse Lighting = off
; Also set Brightness to a low value (1 or 2).
; Disabling XWA's shading system is not required, though, and you can combine it
; with SSDO

; To reload this config file in-flight, just press Ctrl+Alt+L (be aware that
; all key shortcuts are disabled in the hangar, though).

; Main setting to enable/disable SSAO/SSDO. You can also press Ctrl+Alt+O in-game
; to toggle the effect.
ssao_enabled = 1

; Experimental setting: if you see areas of the HUD go white, disable this setting
; SSAO/SSDO/Deferred shading are all supposed to replace XWA's shading system.
; For the best performance, you should disable XWA's diffuse lights; but you
; can also enable the following setting to force the shaders to ignore XWA's
; diffuse component. This setting has no effect in the Tech Room.
disable_xwa_diffuse = 1

; Select either "ambient" for regular Ambient Occlusion or
; "directional" for SSDO (Screen-Space Directional Occlusion).
; "bent_normals" for something
;ssao_type = Ambient
ssao_type = Directional

; Number of samples. The higher the count, the higher the quality (but lower
; performance). Changing the number of samples also affects how dark SSAO/SSDO looks,
; so always start by fixing the number of samples before tinkering with the rest
; of the parameters.
samples = 16

; Distance in meters where the effect will be cut off. Only objects that are within
; this distance will occlude each other. Larger values will impact performance.
; This setting is also used by the depth-aware blur to prevent halos across edges.
max_dist = 200

; Controls the width of the occlusion cone considered by the occludee. A value
; of 0 makes a 90 deg "cone", i.e. it becomes a disk, allowing flat surfaces
; to self-occlude. A value of 1 makes a 0 degree cone, which essentially disables
; the effect. If you want to disable the effect use "ssao_enabled" instead.
; Here the recommendation is to use non-zero low values.
bias = 0.05

; The overall intensity of the SSAO/SSDO effect. Think of this as the "contrast"
; of the effect. A larger value will make whites whiter and black darker; a lower
; value will make everythink gray and dark.
intensity = 4.0

; The effect can be raised to a power to enhance the contrast. Setting it to
; values higher than 1 tends to make smaller and blacker patches. Values lower
; than 1 make larger black spots. Set it to 1.0 to disable it.
power = 3.5

; This defines the blackest level for the SSAO effect. 1 is white, 0 is fully
; black. This setting is ignored for SSDO
black_level = 0.2

; Sampling Radius for SSAO: Controls the spread of the effect. Bigger spreads have
; higher performance impact but tend to look nicer, while a very small spread looks
; like an edge detector. If you're using SSDO, comment this setting out.
;sample_radius = 0.007

; For SSDO, you can set two values for the radius. The far_sample_radius is applied
; at 4km+ away. These settings are resolution-dependent. The following settings
; look good at 3280x2160:
;near_sample_radius = 0.007
;far_sample_radius = 0.0025

; shoot for the middle
near_sample_radius = 0.00525
far_sample_radius = 0.001875

; These settings look good at 1920x1080:
;sample_radius = 0.0035
;near_sample_radius = 0.0035
;far_sample_radius = 0.00125

; Enable perspective-correct SSAO. This makes the settings work only on a narrow
; range of distances. In other words, if you enable this you'll either get SSAO
; on distant objects, or get it on close objects; but not on both at the same time.
perspective_correct = 0

; To speed up SSAO/SSDO (at the cost of quality) you may optionally ask the
; system to perform SSAO/SSDO on a buffer that is smaller than the screen
; size. Set the following parameter to "2" to perform SSAO/SSDO on a buffer
; that is half the size of the screen. Set it to "1" to keep the original
; screen size. You can also use fractional numbers like 1.5.
; Never set it to 0.
ssao_buffer_scale_divisor = 1

; Set the following to 1 to blur the SSAO buffer (removes noise)
; I'm using Pascal Gilcher's pattern for sampling; and it's so good that it sometimes
; does not even need a blur to look good if enough samples are taken. Try disabling
; this setting to see if it looks good for you.
enable_blur = 1

; For SSDO you can have multiple blur passes at the cost of performance. However, I
; don't see much difference above 2 passes
blur_passes = 1

; This shader splits the player's craft/cockpit into its own SSAO buffer so
; that it doesn't occlude distant objects. If you want the regular SSAO you
; can disable it here.
; This feature is not supported in SSDO, set it to 0 or you'll see artifacts.
enable_dual_ssao = 0

; For objects with an alpha mask, the alpha is mapped to solid geometry when
; rendering SSAO. However, this may cause a white halo around these objects.
; To prevent this, the following setting can optionally substract a small value
; to the alpha to soften the edges. If you set it to 0, these objects will no
; longer get SSAO.
alpha_to_solid_offset = 0.5

; Enable indirect lighting for SSDO. Right now there's a significant penalty in
; performance when this is enabled and the indirect lighting effect is subtle.
; If you want to use this anyway, I recommend that you set ssao_buffer_scale_divisor
; to 2 to compensate for the perfomance impact.
; This setting can also be toggled by pressing Ctrl+Alt+P while flying.
;enable_indirect_ssdo = 0

; The intensity of the indirect lighting effect:
indirect_intensity = 3.5

; Due to the discretization of the depth buffer, sometimes you may see moire patterns
; on distant objects when running SSDO. This setting helps prevent these patterns. Set
; it to 0 to disable it (SSAO does not need this setting).
moire_offset = 0.02

; Normal Mapping Parameters for both SSAO and SSDO
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; Enable fake normal mapping for both SSAO and SSDO.
; Pascal Gilcher was gracious enough to share code from his SSR shader that
; helps enable normal mapping by using the current image as a bump map. This
; setting can also be toggled by pressing Ctrl+Alt+N while flying.
; Normal Mapping has been improved a little bit in release 1.1.1; but as a result
; some settings have changed
normal_mapping_enable = 1

; Leave these settings at 1. The intensity is controlled by nm_scale now
nm_intensity_near = 1.0

; If the specular component is too bright, it will "spill out" as bloom. This setting

bloom_glossiness_multiplier = 3.0

; The generic specular model creates a specular component automatically using
; the original color from the texture by boosting/decreasing its lightness and
; saturation.
; Lightness should be numbers above 1 to increase the specular component. A value of
; 1 uses the original color for the specular component, and a value of 0 creates a
; matte look.

; A saturation of 0 provides a white specular component, like plastic and wood.
; A saturation above 1 produces a metallic look.
