What is the impact on Mob spawning if rendering range is small?

What is the impact on Mob spawning if rendering range is small? - Breathtaking scenery of small village located on shore of mountainous island covered with green trees and plants under overcast sky

I have a witch farm. I have noticed, that it rarely spawns witches if my render distance is 4. But, if I set my render distance higher (say to 15) it spawns them at a fairly steady rate. [at the expense of my frame rate, and my play getting very laggy]

I also have a spider spawner XP farm, and I have noticed that the max number of spiders that ever await me when render distance is 4, is on the order of 20, but if I set the render distance higher, it's significantly higher.

Based on the above, I have two (highly related) questions:

1) According to the spawn page on the WIKI, mob spawn caps are influenced by the number of chunks "available for spawning". Is this the "Options -> Video Settings -> Render Distance" setting squared? (or there abouts)? (If so, this would explain the witch farm performance.)

2) Does the mob cap apply to mobs spawned from spawners? (If so, that would explain my spider XP farm issue. I didn't think that was always the case however.)



Best Answer

Render distance affects the number of chunks loaded at once. Fewer chunks = less chances to spawn.

I'm not certain the exact breakdown on chunks / render distance.

Mob Spawners only work when the player is within 16 blocks (the same length as a chunk, incidentally), so since you have to be so close, the relevant chunk (with the spawner in it) will be loaded if its active.

If you're getting more mobs with a higher render distance, you're either a) getting regular mob spawns and attributing them to the spawner or b) mistakenly correlating the effect of render distance and mob count.

Does reducing render distance affect mob spawning?

It's correct that a reduced render distance causes fewer mobs to spawn, but not nearly no mobs to spawn at all. Besides the performance problems there are massive mob spawning problems in 1.14+.

Does entity distance affect mob spawning?

When there are multiple players, mobs can spawn within the given distance of any of them. However, hostile mobs (and some others) that move farther than 128 blocks from the nearest player despawn instantly, so the mob spawning area is more-or-less limited to spheres with a radius of 128 blocks, centered at each player.

What does render distance affect in Minecraft?

Render Distance changes the number of Chunks that are visible from a distance at once. The option has a range of settings which depend on the device used. The minimum (across devices) are 6 chunks, and maximum of 96 chunks. The range is most likely related to the memory available to the device when the game is started.

What is the optimal distance for mobs to spawn?

Mobs won't spawn closer than 24 blocks. They won't move around when farther than 32 blocks. Those are the only rules you need to know for a grinder that relies on mobs walking around.
