if we set  box1.physicsImpostor do we still have to set box1.checkCollisions = true; or can we remove box1.checkCollisions = true; from code?  
	why we need .checkCollisions = true?
 
	Is not box1.physicsImpostor enought to do in code?
 
	Why/When we must do .checkCollisions = true for colliders?
 
	How .checkCollisions = true actualy works in babylonjs engine ?
