Custom VFX

While there isn't a direct way to upload custom "sprites/vfx", you can achieve similar results by importing your own image assets and coding them using the scripting API.

For example, you could upload an image, then make it stretch and scale to match the avatar's movements, creating a trailing effect.

The easiest way would be to make a script that has an array of 2D sprites. Then on update, with a deltatime timer or an event loop cycle through the sprites on a plane object. This can also be done on a custom ui with image source bindings.
