When I bring in a model from Blender the collsion mesh is on it side. If I apply the collsion mesh that on its side when I press play in Unity it cuasese my item to intantly change to face the way the mesh was facing.
Can’t tell what you mean about the collision mesh.
Remove the animation component or child the object to a controlling parent and then rotate the child appropriately. The animation has both movement and rotation keys and so it is moving and rotating your object back to its origin.
