I'm trying to make a animation where, from a clean slate, more and more objects are to appear one after another. I have seen a method where you make the material transparent, but this doesn't seem like a good way to do it... Since I have about 100 object that I want to animate, that all have the same material, I don't want to make a duplicate of the material for every object.

Do you have a better solution for this problem?

Best regards /John

  • $\begingroup$ When ever I have had to do this I simple animate the location from on-off screen over 1 frame. $\endgroup$ – rob Aug 6 '18 at 10:54

  • $\begingroup$ an easy way could have been to create an animation between a Diffuse and a Transparent shader, then in the NLA move the Strip of each object to change the moment they appear, but it looks like, unlike a move Strip, you can't change a Shader Strip position of an object without changing it for all the objects sharing the same Strip, am I right? $\endgroup$ – moonboots Aug 6 '18 at 11:48

If you don't need your objects to appear gradually:

  1. Select your object, go into the Outliner, deactivate the Show In Renders option (camera icon) and create a keyframe (i).

  2. Now in the Timeline move to the frame where you want your object to appear, go into the Outliner, reactivate the camera icon and create a new keyframe.

  3. If you duplicate your object, you just have to move the 2nd keyframe in the Dopesheet to change the time of its appearance.

You can also keyframe the Show In Viewports option (monitor icon) so that you can see in the viewport what will happen in your render.

These 2 options, Show In Renders and Show In Viewports are also available and keyframable in the Properties panel > Object > Visibility.
