Recommendations
To use this mod in the best conditions:
- Use LuaJIT
- Use the default Freetype font style
Troubleshooting
If the inventory's font size is too big on certain setups (namely Windows 10/11 or 144 DPI display), you should lower the
value of the setting display_density_factor in your minetest.conf. Note that the change is applied after restart.
You can also use the font size slider in the inventory, settings window.
Notes
i3 uses a larger inventory than the usual inventories in Minetest games. Thus, most chests will be unadapted to this inventory size. The i3 inventory is 9 slots wide by default, such as Minecraft.
