This will stop objects such as obj fbx max e.
													
																	Imported asset falls through floor unity. 
									
	
		
	
																	I want to make a bouncing ball effect. 
																	It keeps falling through the floor. 
																	But the imported fbx object as prefab falls down as game is started like object with physics component. 
																	It doesn t work. 
															
													
									
	
		
	
																	The mesh does not align correctly to the character the character fell through. 
																	I want my imported object should behave like one created in unity3d. 
																	If your first person character falls through the floor of your game level you may need a terrain collider. 
																	Went to the character and created colliders and imported it as a humanoid. 
															
													
									
	
		
	
																	This happens most often when you fall between the cracks on badly modeled joined terrain due to floating point rounding errors. 
																	One of the challenges i ran into was that when the player moved above a certain velocity it would sometimes pass through colliders. 
																	How to set up collision. 
																	He kept falling trough the floor. 
															
													
									
	
		
	
																	Then added a rigid body the character fell through the plane i then added a mesh collider and attached the mesh for the character to the collider. 
																	I created a plane in unity. 
																	If your floor really is a single solid object the next thing i d check is that the physics loop is running at a high enough frequency that the player can t fall too far into the object before the next tick. 
																	I added a terrain object and gave it a texture to make my floor. 
															
													
									
	
		
	
																	I figure i needed to add a terrain collider and then on the trigger move the rigidbody with a vector force of up. 
																	Model created in unity eg gameobject create object cube is not falling down in y axis. 
																	Sweet then i added a rigidbody to my dude and added gravity. 
																	On the object i added a rigidbody and it already has a box collider. 
															
													
									
	
		
	
																	I m using the official unity tutorial. 
																	How to stop falling through floors and colliders in unity recently i have been working on a 2d platformer which uses the inbuilt unity physics and rigidbodies.
