A new episode for advanced Blender users.
In this video tutorial you'll learn how to animate the render visibility of collections in Blender. This method helps you hide or unhide multiple objects in your renderings by using keyframes in the timeline. My way is easy to setup and very flexible for future changes.
By default you can’t animate the render visibility of collections in Blender out of the box. The internet offers solutions to control the render visibility of objects by using drivers, but this way can get complex and isn't well to understand for everyone.
