Replace

Replaces objects in the current 3ds Max scene with objects from an external file.

• Application menu > Import > Replace

Tip: You can set up your scene and animation using less complex geometry, then use Replace to load more detailed geometry before you render.

• When you replace an object in your scene, you replace its geometry, including its modifiers, but not its transforms, space warps, hierarchy, or materials.
• To replace the object with all its characteristics, use Merge.
• If the object that you're replacing has instances in the scene, all of the instances are replaced with the new object.
• All objects in the scene with the same name as the incoming object are replaced by that object. If you have more than one object in the scene with the same name as the incoming object, all of those objects are replaced.
