BodySlide-and-Outfit-Studio VS Mapbox GL

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.

This is the library here: https://github.com/mapbox/mapbox-gl-native

Yes, I'm using the Flutter MapBox GL project (that uses the native implementation, which is mostly written in C++). I'm using vector tiles, and it's getting down to 1.35cm/pixel for iOS and .12cm/pixel for Android at my latitude; I believe this is level 22 for iOS and 25.5 for Android.

Mapbox has a c++ sdk as well as a GL renderer

But vector tiles is indeed the way to go, but it's also much more complicated. Everyone that has worked on Maps so far has done it either as a SoC / Outreachy student or on weekends and evenings. Look at https://github.com/mapbox/mapbox-gl-native if you want to get a feel for the complexity of a client side implementation of rendering vector tiles.
