Wrong night

Hi,
I having a little problem, I set up correctly a Day and Night cycle based on the real cycle but when it's Night, I feel that the sun shines from below the ground, and clouds appear white super visible and what breaks the mood of the night.

Would someone help me please?

Well, as for clouds there is a code in tutorial:

Code:

// update clouds

   Clouds.layered.update();

   REP(Clouds.layered.layers())Clouds.layered.layer[i].color=ColorBrightness(horizon.max()*(255.0f/164));

You can also adjust the horizon/sky color in the tl table (from tutorial), so it'd be darker in the night hours (between 22 - 6). You can also extend the table (and functions), so it would also be able to change ambient lighting relative to the time of day. It worked for me quite well.

Ok, thank you for that answer, I tackle to try it.

I understood the idea for the clouds but still there as the sun continues to illuminate through the soil, it has nothing to do with the ambPow ();

Look for yourself:

Please help me :/
I have tried many things.

The reason the sun shines through is because of culling. If you look up from underneath the terrain, you will see that you can see right through the terrain, meaning there's nothing to block the light from the sun.

1) Simply disable the light all together ( e.g. Sun.light_color = Vec(0); or Sun.image = NULL; ).
2) Disable culling on the terrain materials so you can see the terrain from both sides (there's the checkbox name Cull on the Material Editor, make sure it's unticked).

Thank you Driklyn for setting, it fixed now smile

Hum, in the Editor, it works but not in play, any ideas?

Try saving the materials and the world if you haven't already. If you disabled the light in the world editor, disable it in code too.
