MoodSettings : Sky/Ambient light

I'm making a space mod for SM and comes the part of the lighting... the moodsettings.xml is great but i've a problem :

As i've a black sky the skylight is black... all parts that are not directly lighted by the sun are toooo dark (black)

so is there a way to set a skylight that not depend of the sky (the ambient light doesn't affect the lighting)

Usually (in other software) the skylight and sky are not directly linked we can set a red sky and a green skylight but here (in maniaplanet) it looks that it's impossible... or maybe that i've missed the way to do that

No you don't have the possibility to trick the lighting engine this way.
What you can try is to set a very high sky bounce, set a sky not totally black, and lower the exposure values to darken the final image.

note : on the moon, the shadows are very black, because the sky is black.

Ok Ty this is what i was trying to do...

And an other question about the moon

We can change the height of the sun with latitude, but for the moon it makes a rotation of the moon around the horizon...
As the moon is blocked on the horizon my lighting is a bit strange

Code: Select all

<Mood>
   <Light EnableStars="1" Latitude="65" DayTime01="0.15" LocalLightX="2" HelperHdrX="0.2">
      <LAmbient Color="d5ffce" Scale="1.18933"/>
      <LDirSun Color="000000" Scale="1"/>
      <LDirMoon Color="5c7457" Scale="1.8"/>
      <T3SpecularLocal ScaleIntens="1" ScaleExponent="1.2"/>
      <T3LightMap MaxHDR="1" BounceFactor="4" SkyFactor="4" SkyUseClouds="1"/>
   </Light>
   <Atmo MoonHdrScale="1" FxSmSelfIllumScaleGamePlay="2">
[...]

_________


And when I use the MoonHdrScale i've some random result, sometimes it change the scale/size of the moon and sometimes it change the illumination of the moon :roflol:

(trying to reproduce it to take screens)

I'm out for some days, I can't look at it right now, sorry. but you can produce some images to illustrate your problem, maybe LuckyBoy can then explain what's happening.

I think the max HDR = 1 can cause some tone mapping oddities (that will make the moon glow "seems to grow".
If your light map has some areas brightly lit and with a value of light stronger than 1, these areas will be clamped to 1, and you can have then a difference of HDR between your other inputs (lightDir value , Sky texture max value, etc...).
you can try a max HDR of 3.

The big moon wasn't an illusion from the tonemapping... xD

Image

The problem here is that the moon is blocked on the horizon (or rotate on wrong axis) even if I change latitude... and if I change the Daytime, the sun is coming around +/-0.25 until +/-0.9
