I have not edited materials, you have to ask it to Rockstar.

I like it. I've seen too many graphics mods that have overly dark shadows and too much contrast. Everything the sun hits is bright, but where it doesn't is too dark. It's like the authors forget that the sun might be the brightest source of light in the sky, but the sky is also a source of light.Not to mention that light bounces off of objects.

I tried about 50 values combinations, and this seems to be the most natural looking setting for the ambient (still needs some tweaks).

I'll explain something about how Grand Theft Auto IV works, to make the situation clear.

 

1) GTA IV uses vertex prelight. It is used to simulate ambient occlusion and/or shadows.

In GTA IV map somewhere it's good, somewhere it's bad, somewhere it's absent. This make the ambient not harmonious, with the same light intensity we can find bright and dark places.

Disabling it does not affect cars, so we will have a bright ambient with dark cars.

 

2) Default GTA IV shaders give the possibility to control metalness only (specular maps), we can't control fresnel or glossiness (like in GTA V) or even highlights. These means we can't have satin materials for example.

GTA IV shaders give us two possibilities: flat material without highlight (RGB 0,0,0) or chromed material (RBG 255,255,255).

 

 

I'll have to rebuild every ground texture (at least the shared ones), a lot of them are completely wrong or bad. Then i'll be able to max out reflexes without have the feeling of playing on a mirror.

Maxed out reflexes = More materials variety = Less flat ambient

 

I have to remake every tree too (at least the shared ones), they look flat, and the tree shader (with the enb) ignores ambient lights.

 

 

 

Comparison screenshots, there isn't any sharpen effect:

Don’t forget that the average luma of each of the three source lights should be 128 (or near this value). Due to the inner calculations in the game engine the average luma of 128 will give the best color perception and intensities. This was discovered years ago by my dear colleague AAA through many experiments. 

 

Anyway, I love these pics of your GE mod. What values would you recommend to use?

You mean luma of ambient 0, ambient 1 and direct light? Absolutely wrong 😁

I tested it few years ago and the result was always the same. A dark luma light with high intensity has the same effect of a bright luma light with low intensity.

Values of? Ambient lights?

 

 

 

New test, this time I opted for a less dead environment but keeping the naturalness:

I did some improvements.

I also started working on texture. This is the difference between default texture (far ones) and default textures edited by me (near ones). This is to avoid to play on a mirror with reflexes maxed out.
