Convert parts of Minecraft maps to Minetest WorldEdit schematics

What you need

• legacy MCEdit
• This MCEdit filter (see below)
• WorldEdit for Minetest

Download: Recommend (mts) / Legacy (we)
Put this in MCEdit folder/filters

Step by Step Tutorial:

1.: Find something you want to convert

2.: Open the world in MCEdit and find it again

3.: Select the area you want to convert

4.: Click the filters tab, select Export to Minetest MTS schematic, enter a name, set options which mods you want to use and click Filter

5.: You should find a file like this, copy it to Minetest folder/worlds/World name/schems

6.: Open Minetest, find an empty area, set pos1, and use //mtschemplace Schematic name. If you have used the legacy filter use //load instead

You don't need minecraft. You only need a world file, MCedit, his filter, and minetest.

Do NOT run any program that doesn't need to be run as root, as root
Also, you need to install pygame and numpy

I can't stress enough how right sfan5 is here, never under any circumstances whatsoever should you run a program as root or admin (as your system may call it) unless there is no way on this green earth to avoid doing so, even if it's a program you trust and/or is by a trustworthy author.

I love this!
Over the last couple of years I made a lot of stuff in Minecraft that I'd like to see in Minetest.
I put a lot of time, energy and love in some buildings and by using this filter they're neither lost, nor do I have to build them again from scratch.

Could you be able to copy MC Servers with this in any way and run them as a Minetest one? Or would that be illegal or something?

Yes that would work

No

No. Unless they have their map under license or something. :P

cool. I think I'll go look up some stuff.

Everytime I try to save my region the program freezes and I'm forced to close.

Excellent, but the sense is that we do the constructions ...

I have used the script to convert large areas such as 640*640*640. The converting process can take some time, my record lies somewhere around 4 hours. The program screen did seem to freeze during this process but I could see the resulting schematic file grow. I was only sure the converting was finished after the schematic file did not change size for several minutes. Maybe a feedback on converting progress and a final "done" message in a prominent way might be usefull.

The only problem with large schematic files though is that the WorldEditor cannot process them as the Lua environment seems to run out of memory at some point although enough RAM memory seems to be provided by the system.

I think converting large maps ought to be better done by working on the map database while the game does not run. That way, it will be way faster and more reliable. There's some promising code at github done by kwolekr, but I didn't get it to run yet.

A standalone tool to manipulate the map database file would indeed be great. Sadly the format used to store the map is a little more difficult than I had hoped.

The positions address mapblocks wich are stored as blobs, which are like compressed folders containing not only information about the positions of the (16x16x16) nodes within the mapblock but also other stuff such as information about the exposition to light. This pretty much makes any off the shelf tools for manipulating sqlite files useless.

For example if I get the light stuff wrong and insert some terrain underground, would the result be similar to this? A generated terrain forced underground by raising the waterlevel for mapgen7

Open what?
If you mean MCEdit.. thatis not in my control

What is with Schematics from Minecraft Worldedit? I have made a Schematics in a FeedTheBeast World, can I drop this Schematics directly into the Schematics folder?

No, MC schematics are entirely incompatible with MT schematics
Also: you should be asking this question in the WorldEdit topic

Is there a way to port things without them being mirrored?

Hello. I have one question. Can be this map converted to minetest (we) or it is too large? http://www.minecraftforum.net/topic/997352-crafting-azeroth/

too large, lua will run out of memory.

do it in sections

thanks for answer. I could not test it becouse i have too slow pc

6.8 GB maps... Jeez. Definitely want to divide that sucker up.

For that amount of data, writing a program to import it directly (or getting that one of kwolekr running), might be less work in the end.

The command //import doesn't exist? I'm using Minetest 0.4.7

Wrong topic. This needs to be moved to the worldedit mod topic.

???

and what makes this dropbox link?

Eh, I think you're in the wrong topic.
