First Person Character falling through the floor

Yes, it has a Box simple collision, I also tried a complex one. Yours seems really fit to the box and mine is a little bit up could it be that? But it should be automatic I think. I’m really glad for your help. I’ll keep trying to solve this, but its so strange since everything seems to be right. If I find a solution I’ll post here, until then I hope someone else can help! Thank you very much :smiley:
