Summary
Cobblemon Veil makes all Cobblemon vanish for individual players in a modded server by typing /hidecobblemon.
How it works
The model is simply not rendered on the client, and if it's installed on the server, you can place blocks where they are!
Client Side only
Cobblemon will not visibly appear or hinder your movement in any way, but if you try to place a block where one is currently standing, it won't allow you to.
Server Side only
Server side only doesn't do anything by itself. but it allows any clients connected to it with the mod installed be able to completely hide them.
Both Client and Server
Having it installed on both allows you to type /hidecobblemon to completely hide models, sounds, hitboxes, and allow block placing where a Cobblemon is currently standing.
