Watch Example Video Here:
Instantly toggle all collections/objects inside of another collection. This will help free up memory by turning off visibility in both the viewport and rendered mode.
By highlighting the collection (so it has a blue highlight) you can then hit Shift+Q to make all viewport/rendered visibility toggles match your collection and also give them a keyframe. This was developed with Archviz in mind, so that you can let a render go overnight and it will help get your under your GPUs memory limit for fast renders. If you hit Shift+T while a collection is selected it will remove all keyframes in that collection.
This was made to work with Blender 2.93+.
