Very dark cockpit in 5.2

[boeingp3d]

Hi,

One of the reasons of dark cockpits is the HDR tonemapper used in the simulator. Physically based lighting calculations often produce values beyond SDR, so it is easier to do calculations in HDR and then convert resulting HDR image back to SDR. Mathematical functions called tonemappers are used for this purpose.

P3D uses Narkowicz fit of ACES tonemapper, which makes the image overly contrasty and crushes blacks. I hope Lockheed Martin uses Uncharted 2 instead, which results in a much more natural look.

Here is my implementation, if it helps:

Code: Select all

float3 Uncharted2Curve(float3 input_color)
{
    const float shoulder_strength = 0.22;
    const float linear_strength = 0.30;
    const float linear_angle = 0.10;
    const float toe_strength = 0.20;
    const float toe_numerator = 0.01;
    const float toe_denominator = 0.30;

    return (((input_color * ((shoulder_strength * input_color) + (linear_angle * linear_strength))) + (toe_strength * toe_numerator)) / ((input_color * ((shoulder_strength * input_color) + linear_strength)) + (toe_strength * toe_denominator))) - (toe_numerator / toe_denominator);
}

float3 ToneMap(float3 input_color)
{
    const float exposure_bias = 2.0;
    const float white_point = 11.2;

    return saturate(Uncharted2Curve(input_color * exposure_bias) / Uncharted2Curve(float3(white_point, white_point, white_point)));
}

Will the shader edits work in latest p3d 5.3 hf2?

I was brave and tried, and the new cockpit shader works in the newest P3D5.3
The fps is a little low during the day on the ground compared to default cockpit shaders but it looks so much better. Thanks BiologicalNanobot for all your work! The combination of edits for environmental haze, less moon reflection and brighter cockpit make 5.3 very good!

Where should the cockpit light tone be placed in the P3D directory. And how should it be titled? thanks

Hello in his post here I used notepad++ to create a new HDR shader file and always delete temporary shader folder in appdata/LOCAL/lockheed martin\prepar3d v5

Checking the folder there is no HDR Shader. And, now it occurs to me that because I do not have an HDR monitor, there would be no such thing...duh, my bad....thanks...

One more question. When I looked at the file being replaced by this new one, I saw that it had been written by TOGA...evidently from my use of ENVSHADE and/or ENVTEX. So, I assume that to use any of the TOGA programs with this new setting is impossible. Is that correct? Thanks.

Hi BiologicalNanobot
Thank you very much for this fix which works fine in 5.3HF2.
Is there a possibility for having better light is the cockpit?
For testing, what criteria must be changed in your fix?
As you, I really hope also Lockheed Martin makes this default in next Prepar3D versions.
