How fast can “Instantiate” spawn prefabs?

I want to spawn multiple prefab objects faster than an avatar can run so that a player can hold a pen object and draw paths while running. I can’t seem to find if VrChat can handle something like that, though. Does anyone know if it can?

It’s not very clear what you’re asking about.

It sounds like what you want is a trail following a player while they run? You might want to think about using a Trail Renderer.

If you want other players to see the trail, then you need some networked objects.

It’s more of a trail in front of them that they can walk on top of. I’m trying to instantiate prefabs with colliders to act as dynamic terrain.
