I'm still curious about those blood-red clouds. Very strange.
That red color in the Rain clouds is an effect from the sun.
Here are notes on sky and sun editing with the bdg text file. Most of these notes I wrote long ago, and I do not fully know what some of the lines do.
This also in the BoBII Manual:Weather_CloudAlbedo= 1.000
Higher number adds more gray to the cloud bottoms. Darkens the sea LIGHT color also. 2.000 is way too much.
Very dark grey areas on the clouds will give an unwanted bad pink color where the sun is.
Determines brightness of glow around the sun. Higher = brighter. No apparent effect on other sky settings.
Determines the sun flare size. Higher = larger. No apparent effect on other sky settings.
These values affect the sky color. Some values can give a whiter horizon while others will make the horizon bluer.
These change the color of the light the sun emits. This includes the glow around the sun, the horizon (360 degrees), and 180 degrees from the sun.
SunLambda and Sky Lambda are RGB values.
All of these settings work in harmony together. You can make radical changes in one area and make up for it in another.
Determines sky and sunglow brightness. Lower (more negative) numbers brighten both. Similar to underexposed or overexposed camera film.
Effects the glow around the sun disk. Lower numbers darken it, higher numbers brighten it. Too high and it brightens over the disc.
Small effect on sea highlighted reflections.
Affects sky color. Higher numbers give lighter blues.
Affects the glow around the sun disk and the Sky Exposure. Higher numbers, brighter.
Heavy effect on the glow around the sun. Best left as –1.500
Unkown. More experimentation needed. Best left as is.
Unknown. More experimentation needed. Best left as is.
Determines sun color. The default setting is “white light” and is best left as is.
This line may effect the red color, too. Higher intensity giving more red-pink showing?
Weather_SunIntensity = 150.000000
Possibly this cloud density line will effect it, too? Never tried that.
Cloud_Inclement_CloudDensity = 254.000000
Cloud Density does have an effect on frame rates, I think. Sun values and sky values do not.
