Note: high values for Twilight level parameter may affect sky rendering during the day.
Different sky textures may require different settings.

Parameter(s):
- Twilight level: Twilight level at which the reducing starts. 0.00 is for night. Range: [0.01 .. 1.00]. Default: 0.20
- Reduction efficiency: The efficiency of glow reducing . 1.00 = max. effect Range: [0.1 .. 1.0]. Default: 0.2

Saturation allows to adjust the intensity of sky color.

Parameter(s):

To add some post-processing effects at X-Plane global rendering stage activate the corresponding shaders in list below.
Activated effects will apply to whole scene in the sim.
This tweak works only in HDR mode.
IMPORTANT: To use post-processing, you SHOULD use antialiasing settings with activated FXAA mode (i.e. FXAA, 2x SSAA+FXAA, 4x SSAA+FXAA, etc.).
However, if you don't need FXAA, just use "FXAA is always off" switch.
To use post-processing, just check the appropriate effect in list and set the parameters specific to the shader.
The order of effects activation could be important and depends on the set. You can change the order with Up, Down buttons.
After applying the shader tweaks, the selected post-processing effects will be installed to X-Plane).
Use "Restore defaults" button to return to default settings for the selected post-processing effect.

Parameter(s):
- FXAA switch. Default state: ON

DPX (Cineon): should make the image look like it's been converted to DXP Cineon - basically it's another movie-like look similar to technicolor effect.

Vibrance_RGB_balanceXYZ [-10.00 .. 10.00] - a per channel multiplier to the Vibrance strength so you can give more boost to certain colors over others. X=Red, Y=Green, Z=Blue

Tonemap: adjusts gamma, exposure, saturation, bleach and defog (may cause clipping).
Parameters:
Gamma [0.000 .. 2.000] - adjust midtones. 1.000 is neutral. This setting does exactly the same as the one in Lift Gamma Gain, only with less control. Default 1.000

Parameters:
Brightness [-1.0..1.0] default level is 0.0, contrast [0.0..2.0] default level is 1.0
When the saturation is 0.0, what you will see is a shade of gray. 1.0 is default level.

SharpenBlurring: slightly sharpen or blurring image.
Parameters:
Strength [-2.0 .. 2.0]. Use negative values to blur or positive for sharpen. Default value is 0.60.
This effect can be FPS hungry on weak hardware.

To add some post-processing effects at X-Plane internal view rendering stage activate the corresponding shaders in list below.
Activated effects will apply only to internal views and virtual cockpit.
To use post-processing, just check the appropriate effect in list and set the parameters specific to the shader.
You can also use expressions with some shader variables as parameter values.
The order of effects activation could be important and depends on the set. You can change the order with Up, Down buttons.
Internal stage post-processing effects will be installed to X-Plane and applied before global stage effects.
Use "Restore defaults" button to return to default settings for the selected post-processing effect.
