VRChat gives you the ability to edit your world. When you edit a world, the scene viewer is updated with the changes and you will see your changes in real time. You can also make any world world or texture file from “res://” (game resources), for example “res://Colour/textures/plate.dds”.

There is no need to download a separate client, as you can run the client and the server on the same machine.
