Distant character not rendered

i am having a problem regarding my multiplayer character who doesn’t get rendered if distant on other clients.
This is not the only problem because when the character is not rendered and the server executes some functions, for example like changing a material on it, it doesn’t get updated on the clients who are not able to see it. Everything works correctly if it is visible from the clients, the problem appears only when it is distant and not rendered.

Thank you for your help.
