ChroMapper VS BeatSaberCustomAvatars

No. You should consider switching to chromapper. You’ll have to switch to the dev release in options for the new note types but that’s it.

Download Chromapper and you can get basic info with the mapping wiki and the Chromapper wiki

You can always build yourself by following this guide: https://github.com/Caeden117/ChroMapper/blob/master/BUILD.md

I used to do a bit of mapping, never released a map, but ChroMapper worked well for the short time I used it on my Chromebook.

https://github.com/Caeden117/ChroMapper/pull/381 the pull request for V3 beatmap support (i.e. Arcs and Chains) has just been merged into the Chromapper code base as a new branch "feature/beatmap-v3"

Mediocre Mapper doesn't support Noodle Extensions. There is a map editor called ChroMapperthat supports Noodle Extensions but it costs $5 because it's in closed beta.

It’s actually quite simple! I currently use a program called ChroMapper which is currently locked behind a pay wall but there are other free softwares to try out! Check out Mediocre Mapper which is free to use! I find these better then the in game map maker XP

Its a mod for the camera, and here's the one for custom avatars

I dont know how to downgrade (I tried using steam console and manifests but it didnt work for me) However i had this issue earlier, I copied my 1.16.1 plugins folder to the main plugins and downloaded BSUtil from github to fix the glitchy menu and most mods are working (its at least playable. I also did the same for custom Avatars as that wasnt working in the new version either.

I prefer the custom avatars mod, so I won't have to show my rolls jiggling to the whole internet

You use Custom Avatars for the getting an Avatar ingame and Camera2 for creating the third person camera.
