FOSS gamedev and creative worlds

Running a singleplayer-game newly made for minetest 0.4.15.
After a few days, I found this new 'black hole' in the countryside just outside my front door:




It looks like a big shadow, but there is nothing that could cause this.

The only notable mod I'm running there is ltools - that tree at the edge of the hole
is an l-system-tree.

Mine a block at the shadow and the shadow will disappear.(I noticed than once in the dwarves subgame to, but I forgot it till now)

I have already tried that, and also cut down that tree, but the shadow remains.

Its a map loading issue that happens every now and then. Avw you tried fixing it with the mapfixer mod?

L-system trees will create shadow bugs when they grow if the mapblocks above it are unloaded. There is a fixing PR being considered right now.

That fixed it, thanks !

Suddenly big shadow appeared on my field. Just in front of my house. I played in this world and in this area for a long time, and everything (lighting) was OK till now.

It happened after pine sapling grows into tree outside the building when I was inside it.

View from roof of my building. There is nothing above, just clean sky.

Placing torch and removing it does not help.
Digging block and placing it back does not help.
Cutting the tree does not help.
Restarting the game does not help.

The shadow is persistent.

Please help.

Many thanks to author of Map Fixer mod. This mod helps me.

As newbie I read what mod generally is, how to install it, enable it, and use it (particularly mentioned mod).

I think algorithms that causes light bugs must be fixed in game itself, not relying on crutches that community make.

More light/shadow bugs on flat surface:

There is a PR being reviewed now that should fix shadows caused by saplings growing.

In latest 0.4.15dev?

0.4.15 from official Manjaro repo, not 0.4.15dev.

Interesting situation.

I have time_speed=0 and time set to /time 12:00.
Well, I don't like night time.

In my house I have a basement which is below sea level. Its walls I made of glass to admire sea/lake bottom. On ceiling in basement there are many torches to highlight basement. Sea bottom is highlighted by sunlight. Now I decided to turn night on (/time 0:00) to see how basement looks from underwater at night. And it turns out that it was very dark. I can't believe it! So many torches on the ceiling but dark floor! While in daytime everything was OK. Is sunlight so influential/powerful compared to torch light? I went to basement, executed /mapfix and… everything around me became lit with bright light! Exactly!

So poor light processing in the game itself!

Advise: turn night on and launch /mapfix to reveal illumination bugs that may be not so noticeable in daytime.

Maybe is this unloading place?Map loads very slowly in MineTest

Also there are like errors has More Trees ModPack

Map block is either loaded or not. It can not be partially loaded with strange shadows as a result of it.

In my case shadow appeared when usual (default) pine tree sapling grew.

I've been using the remove_unknown mod to remove weird shadows. It doesn't show any unknown blocks removed but it removes the shadow weirdness. viewtopic.php?t=11259 Works almost everytime.

err I think I found a random solution I used to get a lot of this and I found by accident a firefly mod that I installed seems to remove random shadows like this I don't know why it worked it just does
https://github.com/4Evergreen4/insects
by the way due to too many bee mods in my game I removed the bee part of this mod so I just run fireflies

Big shadows often appear after using WorldEdit. So install it together with mapfix.
