Here is my custom HDR profile for Lime Rock Park. It should work with all 4 layouts. The zip contains two hdp files. One with a decent bloom at daytime and a profile with bloom disabled.
-reduced autoexposure (fix for the overexposure in cockpit view for the tintops)
-tweaked direct sunlight at day night cycles (reduces the strong red lightning during sunset sunrise)
-high contrast (maybe the trees are to dark if you look against the sun)
-reduced bloom (only the brightest objects have a some bloom)
To install extract the two files to "rF2DataFolder\UserData\player\Settings\trackfolder".
