FOSS gamedev and creative worlds

I want to explore the ocean, but the sea floor is too dark without torch. I want to reduce the ocean darkness, how do I do it? Thanks.

Try adding display_gamma = 1.0 to your minetest.conf (or use the Advanced Settings menu present in Minetest 0.4.14 and later). Lower values make darker areas brighter (the minimum is 1.0).

I change gamma to 1 but it is still too dark for me, any other way?

There's another way by modifying the shaders:
Add the following code to minetest/client/shaders/nodes_shader/opengl_fragment.glsl:


Higher values make it brighter, lower -> darker. This only requires to enable "Shader" but not any of the shader elements.

If your graphics card does not support OpenGL shaders, then edit the source code. For this case, re-compile Minetest after changing this line to

By default light level reduces by 1 per node underwater, so 16 nodes down it will be at minimum brightness and the water post effect colour will overpower anything you can see. You could make water clearer by altering the 'post effect colour' in the node definition.
The only way to make underwater bright is to make water propagate sunlight. add to the node definitions:

sunlight_propagates = true,

This works and is rather pleasant.

Thanks for reply, where exactly do I add the code?

Add that line to the node definitions for 'water source' and 'water flowing' found in:
games/minetest_game/mods/default/nodes.lua

You might also want to add the sea modpack. It comes with luminiscent flowers, shipwrecks, clams and the like and makes the sea bed far more intresting (and bright!) to look at. Also some mobs mod (underwater mobs) are great. There are a lot of fishes and some tiny, beautifuly jellyfish out there - provided you add the right mods :-)
