How to make nights even darker without using gamma?

[adamr]

I don't want to change gamma settings. I just want less light to be cast by the moon, so the night is even more scary. I couldn't find any reference on how to do this. Anyone knows? :-)

It is easy set in minetest.conf:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

time_speed = 0

Now the Sun don't walk.
Then set time to night.

Just change the end of client/shaders/nodes_shader/opengl_fragment.glsl:
