LIGHTING TWEAKS

Sunlight adjustments

Tweak adjusts the influence of sunlight on all objects excluding clouds.
Use it to obtain the necessary scene contrast and change the shade of direct sunlight.
There are two main components: diffuse and direct light.
Diffuse component affects the light intense of shadowed parts; Direct component affects bright areas.
These adjustments do not affect clouds lighting

- Direct sunlight power: Higher power value means more direct light. Range: [0.1 .. 20.0]. Default: 5.5
- Direct sunlight saturation: This parameter affects on direct sunlight tint. Increasing this value will give a more intense shade of direct sunlight. Range: [0.1 .. 3.0]. Default: 1.0

Example 1: Diffuse light power changed to 1.5:

Example 2: Diffuse light power = 0.5, Direct sunlight power = 10.0:

POST-PROCESSING TWEAKS

Global stage post-processing

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

Tweak has the following potsprocessing effects:
