I want to make an animated GIF of a 7-storey building in which the storeys pile up one upon another until the whole building is complete. I know it can be done with Photoshop but it entails a fairly complicated process.
My question is: can I do it online or using an app the easy way?
You can use LICEcap to make a .gif of your screen, in which you could be actively revealing successive stories using tags in realtime as it records the SketchUp Window.
Or you could use scenes and tags together to make a series of scenes which reveal successive stores then export that animation and use a converter to change the video format to .gif. The advantage of this is you could also incorporate preset camera moves into the video which adds drama.
Or, you could use scenes and moving section planes to reveal the stories, and then export that via export animation. This method would make progressive reveals of each story that wipe upward instead of jumping by story as tags would do, for a different smoother look. Then convert to .gif.
I’ve done simple animated gifs before. Similar to whar @endlessfix said to do, you could also use tags or hidden objects saved to scenes…export and animation to MP4 (I see you’re on Mac)…and use something like Gifski to convert it to a GIF.
It is an extra step but another way as well is batch export all the scenes and add to a video editing program, add transitions, like a simple cross dissolve…and again, export to MP4 and convert to GIF. I did that with this build up below:
Edit: for more complex animations, check out fredo animator…that would allow more than just turning visibility of objects on or off…but you can actually move, like have the bldg floors ‘drop’ into place and more.
We use Keyframe Animation by Regular Polygon - the following link is one of their sample animations which might be along the lines of what you want to do: https://youtu.be/B1X4tblcmdY
