How to make objects disappear from animation in blender

$\begingroup$

I am creating a small antimation, where I need a few objects. One which is text to appear then disappear, and one object to disappear at a given frame setting(s).

I know the eye button in the outliner can do this, but how do I work that in using key frames?

In Blender Internal you may achieve it keyframing the alpha transparency values. E.g. in frame 1 hover the cursor over the Alpha slider with the value set to 1.000 and press I to keyframe it. Then go to frame 2, change the alpha value to 0.000 and keyframe it again.

In Cycles you can keyframe the Fac value of the Mix Shader (which mixes your shader with Transparent shader).

Lets say you want to make something appear in frame ten and then dissappear at frame 20. At frame 0 go to outliner and click camera icon (eye only hide things from 3D view, not from render) and press "I" while hovering still over the camera icon and you see that it create keyframe for it. Now go to frame 10 and click camera icon again to make it visible on render and while hovering over press "I" again to make keyframe... at frame 20 do same that you did in frame 0. I have used to make keyframes for both, eye icon and camera icon, so same things would happen also in rendered view and in 3D view.

I'm quite new to blender, and I'm doing some experiments with it.

I've been searching for a way to make an object disappear from sight at a particular key-frame, without moving it out of the camera view. E.g. at frame 1, cube is there, at (0, 0, 0) and at frame 2, it's not visible anymore, but still there at position (0,0,0), at frame 3 it gets visible again.

After searching the web, I came upon this page which suggests to move the object to another layer, but since it applies to blender 2.49, it seems the software has changed since then: I'm unable to find the 'Layer' option when inserting a key-frame.

I've found some other sites but either they suggest to use a technique similar to the one linked above, or they suggest to change the alpha of the texture, which I'm not interested in.

So, what's the preferred method to make an object invisible in blender 2.59?

Additional information (not relevant for the answer I'm expecting, IMO):

• I'm using blender to make models for Unity.
• I'm using 2.59 because that's the one that works with the unity version that I have.
