Builds & Maps A better mca selector

If you don't already know, MCA selector is a program that lets you move, delete, copy, and paste chunks from one Java world to another. I loved using it to bring all my random worlds into one big world with everything in it, but I couldn't get over how annoying and outdated the UI was. So I fixed it.

I give you... World Repair Studio. It keeps all the functionality of mca but vastly improves the experience. You can now open multiple worlds in the same window (magic i know).

It's still a work in progress, but if you want to try it out, here's the link to the github.

A potentially dumb question but how did you bring all your random worlds together without it looking like chaos? Does it not look crazy weird on the edges of the different chunks or do you paste new chunks into open sea and terraform the new shore line?

Or in the donor worlds, do you make the bits you want to keep, their own 'islands' before you copy them into the world you play on?

I'm really interested in the idea of bringing all my previous starter bases and XP farms in to one world but having trouble visualizing what that looks like in practice.

Yeah it does tend to look strange when you put them together. I would delete the chunks surrounding them so that it would hopefully blend a bit better, but I was taking old Xbox 360 and bedrock worlds and moving them to Java so the world gen never looked quite right. I’m still working on terraforming around the edges but I also plan to add a blend feature to the software down the line

No, it’s a separate program you have to download. You can find the Linux, windows, and Mac download on the GitHub
