Project Arrhythmia is being rebranded to "AfterBeat". However, #betterlegacy related things will continue using the Project Arrhythmia name, the PA acronym and #projectarrhythmia tag.
If someone asks what game it is please direct them to AfterBeat.
If you have any questions about it, please ask!

Was trying to implement a level recorder / video exporter (for anim difficulty) to the #BetterLegacy mod for the Legacy branch of #ProjectArrhythmia, the furthest I've gotten is actually running the ffmpeg program but after that it doesn't do anything. Any ideas on what might be happening #gamedev?

After a long time, there's a brand new effect: Shockwave!
This works similarly to the Shockwave effect in Geometry Dash.
(fun fact this is actually the first effect in BetterLegacy since the glitch effects were in the older mods)

In the #BetterLegacy mod for #ProjectArrhythmia, you can create navigate-able levels, alongside rooms that can be culled out when the player is not near.
Also, each room is a singular prefab with different modifier settings on each of them.

Decided to port the Prefab preview feature from the modern #ProjectArrhythmia editor to the #BetterLegacy mod. However, it works a little different here.
In this version, you can set a custom icon via a JPG or use the new capture area feature.
(btw yes I have so many character models oh god)
