Troubleshooting

This page lists common technical problems like crashes and error messages (enclosed in quotation marks) and possible solutions or explanations. For general questions, refer to FAQ.

Graphics and sound

The screen is too dark

There currently is no easy solution apart from changing monitor settings, you will have to edit a text file. This only works with shaders enabled. Open (Minetest directory)/client/shaders/solids_shader/opengl_vertex.glsl with a text editor, go near the end of the file, change these lines:

color.r = clamp(rg,0.0,1.0);
color.g = clamp(rg,0.0,1.0);
color.b = clamp(b,0.0,1.0);

to:

color.r = clamp(rg,0.4,1.0);
color.g = clamp(rg,0.4,1.0);
color.b = clamp(b,0.4,1.0);

You can try other values instead of 0.4, the higher the brighter.

Everything in the game is in a weird color (particularly red), looks like rainbows, can partially see through things

Turn off shaders. Shaders are not supported by your graphics card.

There is no sound under Windows

You need to download OpenAL to play sound on Windows (the file needed is [1], you need to execute the program after it has finished downloading. Firefox and Chrome users may need to either save file or keep downloading, Internet Explorer users will need to just press run. Other browsers maybe the same or different. If one browser fails, try another.)

Error messages without crashes

“Unsupported texture format”

Don’t worry, this is completely normal. Minetest will still work.

“Generating dummy image for […].png”

This means that a faulty mod or texture pack does not supply an image for an object. Minetest will still work normally, but the specified object will use a replacement image (the “dummy image”); it will be a random color. This should normally be reported to the author of the mod or texture pack.

"ERROR: No world name given or no game selected" in create world

You need to select a game name in the list box in the create world dialog.

Please before the click of the "New" (to create new world), select the icon at the bottom ! (you need choose)

- Logo minetest ( Minetest Worlds )

- Cartesian coordinates ( Minimal Development Test - Worlds )

There may be more icons available if you installed more games.

Crashes

All sub-section titles in double quotes here mean that Minetest crashed with an error message like that.

Any operating system

“Minetest can not load […]/init.lua”

Follow these steps, stopping when the mod works or if you reach the end Make sure the mod folder is correctly named. Find out the correct name by going to the mod's forum page and looking at what is in the [ ] in the title. Report the error to the mod owner by copying and pasting the section in debug.txt that starts with "=====ERROR FROM LUA=====" if any.

“Assertion '0' failed”

This is usually a mod error. Report it to the mod programmer or mod programmers. To find out the name of the mod, look for any error text directly above that gives a path to a mod's init.lua

 ERROR: An unhandled exception occurred: LuaError: error: mods/minetest/<modname>/init.lua:69: [...]

“ServerEnvironment::loadMeta(): EnvArgsEnd not found”

Put something like this in env_meta.txt in your world folder

 game_time = 40053
 time_of_day = 20068
 EnvArgsEnd

it doesn't matter much which numbers you use.

Windows

“MSCP2010.dll is not found” (or similar)

This is because Microsoft C++ Redistribute Package 2010 is not installed. [2]

Minetest doesn’t even start

If it stops working before the main window even opens, and there are no error messages in debug.txt, then try restarting your computer. (sometimes it crashes with a 0x00005 error, which is caused by windows updates.) You can try looking in debug.txt for an error message or searching for a similar article in the forums.

“what()=Access Violation”

This is caused by the Direct3D driver. To fix, go to the minetest.conf file and find:

 video_driver = direct3d9

change it so that it says:

 video_driver = opengl
