i have imported sktechup object inn unity. then i have apply the box coilder on a object but itishowing far away from the object i have try to rescal it and adjust it on a object but its not work. actually i want to movie and transform it in VR. thats why i am using ray caster with a camera. So,the rays will pass through the object because there is no any colider on a object.
Solution 1: Move Center of your box collider and resize it.
Solution 2: Add empty gameobject to you object as child. Set its(empty gameobject) position to the center of your object. Add box collider to that empty object and resize it.
