How to Completely Disable Eye Adaptation (Guaranteed Method) - 5mods/tutorials GitHub Wiki

Essentially pretty simple this, just a little time needed to configure & find the correct brightness/exposure value/s to use, but guaranteed to work & disable eye adaptation completely. Like completely disable it, zero, none, nada, off, gone, bye, dead :thumbsup:

Method:

Basically, the '<postfx_exposure_min>' & '<postfx_exposure_max>' values in the timecycle files ('w_clear.xml', 'w_extrasunny.xml', ... etc) control the range of brightness/darkness Adaptation is able to use. So setting them to the same value (whatever that value may be) for any given time of day, completely disables Adaptation's ability to change the brightness of the screen for that particular time of day.

Example (Adaptation disabled throughout all (13) different times of day):

<!--            Time of Day           0      5      6      7      8      9      13     17     18     19     20     21     22 -->
		<postfx_exposure_min> 3.8500 0.5000 0.5500 0.5700 0.5800 0.5900 0.6000 0.5800 0.5700 0.5600 0.5500 0.5400 3.8500</postfx_exposure_min>
		<postfx_exposure_max> 3.8500 0.5000 0.5500 0.5700 0.5800 0.5900 0.6000 0.5800 0.5700 0.5600 0.5500 0.5400 3.8500</postfx_exposure_max>

Key Points:

To Disable Adaptation:

• All that matters is that the values for '<postfx_exposure_min>' & '<postfx_exposure_max>' be the same for any given time of day.

For Brightness Tweaking/Recreating a Timecycle Look:

• The higher you set the '<postfx_exposure_min>' & '<postfx_exposure_max>' value the brighter the screen will be.
• The lower you set them (can be negative if required) the darker the screen will be.

Note: The exact value/s that you use for '<postfx_exposure_min>' & '<postfx_exposure_max>' for any given time of day, will be specific to your game & visual setup. Copying my example values above will likely result in a screen that is too bright or too dark to be ideal. You could perhaps use those values as a starting point, or as a quick test to confirm this method works, but ultimately, you'll have to find your own value/s that work for you. :thumbsup:

Screenshots - Before & After Comparison:

As you can see from these screenshots, once you find the right value/s (for your game), it's entirely possible to get your weather looking nigh on identical to how it was before:

ExSunny - Day (Before):

ExSunny - Day (After):

ExSunny - Night (Before):

Note: For the comparisons above I only used minimum increments of 0.0100 to find a brightness close to what I had before. Obviously, it's entirely possible to edit in smaller increments for a more exact result/match. Doing so, I'm pretty confident it would be possible to recreate a truly identical look.

So, in short, using this method, it's entirely possible to re-create a timecycle look that's indistinguishable from the original, while also completely 100% disabling adaptation at the same time. :thumbsup:
