Hi all,  
I am using getObjectsUnderPoint to know if an object is colliding. I need to hide the objects to collide with, however if I set visible property to false getObjectsUnderPoint does not work because the objects are inactive.

How I can not render an object and the same time to let it be active?

If I render the original object over the object to collide with, this will take computing resources?

Thanks in advance
