I can't seem to find some files. For example, in the folder "prologue" folder of the vanilla game, I can only find env_prolog_colors_cinematic_tonemapping, but not env_prolog_colors_v1_b_sunset.
I edited env_prolog_colors_cinematic_tonemapping so far, but there's values things that are not in the vanilla file. For example, under m_water, there's no "+" sign for underWaterFogIntensity. Your mod however does have such a category. There's also values some categories where the mod has more subcategories (such as for example 0,1,2,3,4 instead of just 0,1). I only changed what I could compare, and then saved.
I hope this is accurate and will work. I have no idea where to get the "missing" env files from though.
There are actually a lot of env files I can't find. I hope I didn't make any mistakes while uncooking. I used quickbms with the included script file from Nexus, and I just selected the "content" folder of the base game (by navigating to TW3 directory and then typing "content"). I thought that should uncook everything.
