I’m trying to make a simple animation of a sort of fractalated tree “growing”. Is there a way I can just make an object suddenly exist at a certain keyframe, instead of hiding it inside another object?
Keyframe it moving from an invisible layer to a visible layer
or
Keyframe its renderability in the outliner (camera icon)
or
Keyframe the objects transparency from transparent to opaque
or
Keyframe an objects scale from 0 to 1
If it was me I would prefer keyframing visibilty (on off) as growing could affect motion blur within a frame (same with sudden movements caross frame) resulting in weird ghosting.
