add/remove 3d object dynamically

[spirit126]

Is it possible to add/remove objects dynamically?

For example, when a person joins. Is it possible to add his avatar to the scene?
If yes, is a renderer necessary for this?
If a re-render is necessary, how do you prevent animations from being spotted?

Hi Markus,
Issues like this in R3F scenes often come from heavy geometry, material setup, or glTF export configuration. We have helped teams smooth out similar problems by optimizing the model and textures for runtime performance.

If helpful, happy to share a quick checklist you can try.

In R3F you use conditional rendering, same as a regular React component. The fiber reconciler handles adding/removing from the Three.js scene for you.

When a user joins, add them to the array. When they leave, remove them. R3F mounts and unmounts the mesh, geometry, and material. No manual scene.add() or scene.remove() needed.

Animations tied to each avatar live inside the component and clean up when it unmounts.
