Object collides everything

Hi :slight_smile:
I’m fairly new to unity, so excuse me if that sounds obvious…

My player seems to collide every object in my scene… even those who have no collider at all.
It uses a mesh collider. I tried to use a box collider instead (not the best choice for me), but to no avail…
I’m pretty dazed by it.
Any suggestions?
Thanks

Could you send a pic about the scene view of your game?
