My Character Fall Throu The Floor Unreal

My character always falls through the ground in my game.
My character fall throu the floor unreal. On the object i added a rigidbody and it already has a box collider. One of the challenges i ran into was that when the player moved above a certain velocity it would sometimes pass through colliders. I have a simple actor that only has a static mesh and after i set it to simulate physics it drops through the floor. This would lead to the player getting stuck inside the floor when landing a from a.
There can be several reasons why your character falls through the ground. Once the objects is on the floor it can move around without falling through the mesh itself does not have little holes or missing polygones. Recently i have been working on a 2d platformer which uses the inbuilt unity physics and rigidbodies. It keeps falling through the floor.
I tried to make it land on a skateboard when the game starts but the skateboard just slips away and they both fall. Please help my game is dying. The floor has a mesh collider the falling objects box colliders. So the feet of your character start to sink into the ground and when you grow your capsule it will clip through your level and fall down due to gravity.
I put character physics on it so it falls but it always goes through the floor. Or you can make a script that moves the character using the wrong api calls or even call them incorrectly. To get the best support from the community a screenshot of your setup usually helps. The problem is that just shrinking the half height is probably not what you want when your character is crouching because your collision capsule is shrinking from the top and the bottom.
I want to make a bouncing ball effect. I ve tried replacing the default scene root with static mesh since i think it does change something but to no avail. However my object falls through the floor. For one you can set up layers that makes your character ignore the terrain.
Sometimes a falling object does not collide with the floor but falls through it.
