Keyframing opacity in Blender is a way used to manage the transparency of an object over time. This may be helpful for creating results similar to fading in or out, or for animating the visibility of an object.
To keyframe opacity, first choose the item you wish to animate. Then, within the Timeline view, click on on the “Opacity” channel for the item. This may create a keyframe on the present body. You may then transfer to a special body and alter the opacity worth. Blender will mechanically create a brand new keyframe at that body.
