Display other players' actors as ghost

Hi all,
I am working on an online multiplayer game. In this game, for me as a player, I want to see other players’ characters/actors as ghosts only, so that I know where they are, what they are doing, etc. I don’t want them to interact with my own characters/actors. And I want this to be happening for all the connected players in the game.
Any idea about how do I approach this?

Thanks,
SP.

Hi man, so every player see everyone but noone can interact with others .
Well for the interactions i think you are talking about collisions,
that should be simple as you can setup that you can collide with the level , but not with other players.
A ghost shader is easy too, is full of tutorials, you choose to draw other players behind walls too! to see every-player everytime.

I dont know the type of game you plan but beware the “middle object” like a door, if players can open and close door, you can indirectly interact !

Hi @Est_engine,
Interacting part is clear to me, thanks for that.
The game I am trying to make is like Trackmania, in which I want to see what other players’ cars (actors) are doing, but don’t want them to interact with my car. This effect is shown here.
Sorry this part is not create to me yet.
Thanks,
SP.
