This mod is an implementation of held item illumination that produces a certain level of light depending on the luminescence of the player's held item.
Since it checks node definitions for light_source values, no configuration should be needed.
Also, the internal code has been fine-tuned to reduce the amount of visual bugs, mainly by being as thorough as possible when trying to find a suitable position to emit light from.
Great mod, but there is a better Version
To anyone looking to install this mod,
mt-modsmade a better version of this modSimple mod but great game changer.
This mod provides great quality of life improvements to Minetest.
Works okay but outdated
It does what it claims to do but by now we have much better alternatives. There's an updated version of this maintained by mt-mods but I recommend to instead download wielded_light. It has many more features, runs very efficiently, and offers an API for other mods to extend its functionality.
