Releasing my newest Blender addon, nView! It automatically hides or reveals objects in your scene based on their visibility from the camera. It can even include objects that are only visible from a reflection (such useful if your scene involves many reflective objects). Supports all object types as well as instanced collections within objects.
Useful to control and improve performance of your scene, both in the viewport and a render.
