1) How long are nodes like sand or dropped items falling in singlenode mapgen? Infinite or are they removed after a certain time?
2) How far does flowing water/lava fall? Infinite?
3) Is there a diffence between air nodes and other nodes if they get saved?

2) Until it reaches the ground; maximal 64k nodes
3) air is saved - ignore isn't

thx that was fast :D
@3) what is the difference of air and ignore?

@3) you can walk through air and replace it with another node. ignore is solid and used to stop you walking into not loaded areas

Ok! Thank you very much! :)

I have questions about singlenode myself.

Why do nyan cats spawn for? Isn't it supposed be nothing? and why some areas are darker then others?

That all I got really.

Nyan Cats are spawned by the mod “default” of minetest_game, not by the map generator itself.

I cannot answer the other question. Maybe because of a bug? lol

Cats are spawned because they're cool, and transcend all dimensions.

And it's not possible to trace the meows of the mapgen by overriding default.make_nyancat. l tried it and still don't know the reason.

Another question:
Is is possible to force the mapgen/game not to replace ignore nodes with air? In other words: Is it possible to force a area to keep unloaded like the sky above the cloud layer?

Once an area is generated, it doesn't matter how it's filled.
The sky above cloud layer is loaded like any other block.
You can use a new function to delete a specific mapblock

Doesn't item_entity_ttl only limit the time for item entities only? So I guess this does not apply to falling nodes, because they are not item entities. Right?

I thought he meant dropped stacks which fall down.
It would require an addition of 4 - 8 lines of code to add a maximal age for falling nodes.
