Unexpected pregen behaviour

[thisischrys]

I've tried pregenning with and without setting the optional coordinates (used 0 0) as well, but I end up getting something like this:

where the area that was pregenned is far away from spawn.

Documentation is a bit sparse, I assume the numbers it takes are chunks, not blocks?

Hi,

Can you let me know what command exactly you ran - and what dimension you are pre-genning too?

Did you do it from the server console or from in game?

Are you running anything like Sponge on your server?

Thanks :)

I ran /chpregen world 200 200 1 false at first, assuming it to start at spawn. (is that right?)
I was counting on dynmap 2.6 alpha for 1.12.2 to show me updated chunks after a fullrender, but it didn't so I ran
/chpregen world 200 200 0 0 1 false
to see if that would help, both from inside the server console

Dynmap not showing the chunks ended up being an issue with it, the latest 3.0 alpha solves it (and revealed the chunks near the bottom to me)

I DID have sponge on at some point when I first used it, but I've removed it since (the latest version crashes on startup)

I'm not sure if I've run it since removing sponge, I'll give that a try if you think it's useful.

Are you actually typing "/chpregen world" - or are you specifying a number - the dimension ID?

Can you also let me know what version of the mod you're using?

[thisischrys]

you're right, it was chpregen 0
world is what I use for dynmap fullrender
I saw output from it running and from cascading worldgen

it's the latest version: 1.10.2-1.8.7

I'm running it again now to make sure it wasn't sponge.

[Cloudhunter]

Thanks - let me know how it goes. If it is still dodgy it's obviously something derpy in my code - got my suspicions (I could be using a block location as a chunk location, which obviously won't work right), but this will confirm!

[thisischrys]

Ran chpregen 0 200 200 0 0 again, it's generating chunks around the area it did before again as far as I can tell.

Thanks! Can't look at fixing it right now but will soon - can you provide the seed for your world so I can try it out myself?

I also presume that you haven't changed the world spawn using commands or otherwise from the default?

[thisischrys]

I haven't changed the spawn at all no, but I do not use the default world generator, I use realistic from Quark if that matters. Seed 558680760

I have quite an extensive modlist ( http://bonemarrowcold.com/minecraft/mcu/sas.xml )
I assume you don't see this behaviour without any mods? Haven't tried it.
I appreciate that it could be any combination of mods, I'd be willing to do a binary search to find the culprit time permitting.

[Cloudhunter]

Honestly doubt it is mod related, but I'll let you know when I've investigated it (after this weekend).

Thanks for the report!

Hi,
Not the OP but i was interested if this issue has been investigated further and what the result was, I wanted to pregen my server world but i'd like to wait to hear back if this issue is resolved.
Thanks and sorry for hijacking this thread!

Ping? I will probably just go with something else that I know works, but I was going to give this a try. I'm not going to unless this is elaborated on, and I suspect doing so may convince people after me to use it if it's confirmed to now be working. 👍

[temotodochi]

Apparently not fixed. I did a pregen on 1.12.2 ftb revelations for 500 chunks around the spawn, but chpregen decided to use 0, 4000 as zero point as seen here https://zyrain.org/revelationmap/
or if that's not visible, capture with zero point marked is also here https://imgur.com/Xssncqv

Looking at the code the Pregen will always start at world spawn.
/chpregen dimension, minX, maxX, minZ, maxZ,

As far as I can tell this is working as intended.
