This feature is simple – you can clone yourself in multiple/different avatars

The ability to create an animated clone of your avatar that replicates all of your movements locally(only you can see it). It features a "Record" option in the radial menu that allows you to record your motions indefinitely and a "Stop Recording" option that allows you to create an animation that plays indefinitely until removed. The clone includes toggles, visemes, blend shapes and physbones interactivity.

The ability to create a frozen clone of your avatar that replicates your exact pose. You can either set a timer or hit a button to instantly clone yourself.

The capability to add an unlimited or limited number of clones, including the ability to remove clones individually or by "first created" or "last created" in their radial menu.

The ability to view cloned avatars through the camera.

If you change your avatar the clone's avatar will stay the same.

The viewing of cloned avatars is local by default, but you can choose to show specific friends clones.

It makes it possible to create higher-quality VRChat content (video, projects, and filmmaking production) conveniently and efficiently.

It allows VRChat Players to assess their movements in real time from a third-person perspective.

The player base

This was originally a mod known as Freezeframe (https://github.com/Er1807/FreezeFrame) that many at the time utilized to make amazing groundbreaking creative videos/photos that otherwise wouldn’t be possible, or would require many players.

This will be optimized by acting like static objects. Which means meshes are baked so they’re no longer skinned meshes.

Including shadows in the clones avatar would help with realism
