The base of every gameobject shake

Hi, so im making a rpg game and im placing stuff on my terrain(tree, 3d model, etc...) and after this i run the game but every stuff that touch the terrain shake at the base(where the contact occur with the terrain) like for example the base of my house when i look at it shake but if stop moving the camera its all fine and in the editor too so i dont know if its the camera or the terrain the problem. Ive been looking everywhere but i cant find the solution.
