This is a mostly frozen copy of the Minetest forums through 2017. If you know phpBB3 and would like to host any G-rated forum here, you can email: me@minetest.org
If the email doesn't work, find out who's taken over Final Minetest from OldCoder and email them to get write access or an admin account.
I should have set this up years ago. But it's no tale of woe.
Whether the temperature is high or low, regardless of cold winds blow,
away we go like Edgar Allan Poe, on now with the show. BTW rhymes are welcome.
A hacky way: Use a vmanip, copy the data of the area, replace it by air only, write to map, update_lighing(), then place the original data and write to map without calling update_lighing().
It would be better if you would have used vmanip for the first placement.
Yeah but rewriting my mesh spanwer thingy to use vman would be a huge undertaking when simply disabling update_lighting for add node would do the trick (either as a function parameter or a separate function entirely)
