How to Spawn and Clear Client-Side Entities

You can add or remove entities strictly within your own client world. This is useful for checking how a mob fits into an enclosure, testing sightlines, or clearing visual clutter from crowded areas on your screen.

Summoning Local Entities

Open chat and run /vsummon followed by the entity arguments you want to spawn. Because the entity only exists on your system, no other player on a multiplayer server will see it or interact with it.

Keep collision mechanics in mind when spawning mobs near ledges or hazards: you can still be physically nudged by client-side entities. On a multiplayer server, getting pushed around by an entity the server does not know exists can interfere with your movement, so stand in a safe spot before summoning mobs right next to yourself.

Removing Entities from Your Screen

When you want to clean up entities you spawned with /vsummon—or temporarily wipe existing entities from your local view to reduce visual noise—run /vkill in chat.

Because /vkill only removes entities from the client world, using it on a multiplayer server will not actually slay real mobs or destroy items for other players; it simply clears them from your local client.
