Minetest comes with an additional package minetest-usrdir_patch, which should patch some file to find the textures.
I downloaded the following textures from the minetest forum and installed it to
/usr/share/minetest/mods to make it available system-wide: homedecor_modpack, mobs_animal, mobs_redo and unifieddyes.
I also tried to copy unifieddyes to
However, unifieddyes cannot be found, and mobs_animal can be found only be … some users???
Both directories have all files’ owners set to root:root, and permissions o+r.
Does anyone know how to make it work reliably?
