Keyframing opacity in Blender is a technique used to control the transparency of an object over time. This can be useful for creating effects such as fading in or out, or for animating the visibility of an object.
To keyframe opacity, first select the object you want to animate. Then, in the Timeline view, click on the “Opacity” channel for the object. This will create a keyframe at the current frame. You can then move to a different frame and change the opacity value. Blender will automatically create a new keyframe at that frame.
