the player "enter" into the ground

I have the following problem:
When I press play the player goes halfway into the ground:


The model is formed by more mesh, but each has its own collider.


what is the problem?

 

Not sure but you might try zeroing the model to origin(0,0,0),creating an empty game object and making the model a child of the empty,then moving the empty up till model is where you want it.

 

Is the !owed collider maybe set to be a trigger instead of a collider?
