BodySlide-and-Outfit-Studio VS skyui

How exactly are you exporting the files and are you following this: https://github.com/ousnius/BodySlide-and-Outfit-Studio/wiki/Packing-projects-for-sharing

Then follow this guide.

Handy guide for installing bodyslide. The most important thing being that you download bodyslide and install it through Mod Organizer 2, then you run it through Mod Organizer 2.

I'm specifically interested in the Park Survivor outfit but getting bodyslide for any of them would be awesome. Alternatively, if anyone has a noob friendly guide on how to do this I could attempt it myself. I tried using This guide but I couldn't get any sliders to appear so I gave up.

I just recently learned how to use conversion references for converting outfits in Outfit Studio thanks to the guide on github. But some armor pieces still don't fit well on the CBBE body and I was wondering if the process is the same or different.

Grab the SkyUI sources here, for other mods they are usually includes with the download or on the Nexus.

This is a better link than the one I originally gave. I'm going to edit my original reply to use that link. I verified that the download works for SkyUI SDK 5.1 which is probably the version you need.

SkyUI SDK on Github, includes some example scripts.

4) Open the SkyUI translation file (with the same language) from https://github.com/schlangster/skyui/tree/master/dist/Data/Interface/Translations (click on the file name, click on the Raw button)

This won't help you, but I'd like to mention anyway that the MCM has key conflict detection support built into it, but it has be setup by the mod author when they're creating their MCM. If everyone did this correctly, you wouldn't have this problem. Key Conflict Management is discussed in the MCM Advanced Features.

You need the skyui sdk it contains ski configbase

Assuming you have covered the ground for basic Papyrus scripting, there is the MCM API documentation which covers regular implementation of an MCM, including standard examples.

Are you a mod author interested in using MCM? The Documentation explains how it works.
