Scene Animation Set-Up

You can create the illusion of an object moving by creating multiple copies of the object positioned incrementally along the intended path of movement, saving each copy to a different Layer and saving each change on a different Scene.  In many ways the method is akin to Flip Book animation.

  • Each instance of the object is assigned to a unique Layer.
  • The visibility of each Layer is controlled by the Saved Properties of each Scene you create.
  • Camera Location remains static from Scene to Scene.

Below are some noteable tutorial showing how to set up Scene animations.In order to thoroughly examine the SKP files, open the Layers browser (and/or Entity Info and the other control panels like Shadows and Outliner) while reviewing the scene animation tutorials below in order to study the changing visibility of different elements in the model. 

Slideshow animation settings are located at Window > Model Info > Animation.  Right-click on a Scene tab and select Play Animation to run the slideshow.

  • TV Mount  George Knowles - 3D Warehouse tutorial on the use of Groups, Layers and Scenes to articulate parts.
  • Fabric roof  Look for the tent_bb3.skp file.  Create a slideshow animation by placing geometry on different layers and changing layer visibility on each Scenes, animation shown below.  (Quite a few of the models shown in animated GIFs on this website - and the Scene set-up to create the animation itself - used a variation of this method.)
 
 

The take-away from studying tent_bb3.skp

Below are a few examples, heading several pages on this site, which owe their creation to the knowledge derived from the Layer/Scene set-up done in tent_bb3.skp example - a little file shared by someone in a forum thread a few years ago....

Tips: Anyone who may want to set up a scene animation will end up loving the plugin Add Hidden Layer by Jim Foltz.  The plugin lets you add content to a new layer which will be invisible by default on existing Scenes - a big time-saver on files with many scenes as you will not have to update Scene layer visibility every time a new layer is added.

For any camera position tweaking that needs to be done - and saved - between Scenes, Camera > Previous is quite useful.  The option cycles through the last few camera positions.  It's worthy of adding as a custom keyboard shortcut through Window > Preferences > Shortcuts.

 Edit > Paste In Place
Edit > Paste In Place is quite useful for people want to scene animate grouped (or componentized) bits and pieces of geometry.  Copy a group/component then use Paste In Place.  Move that copy into a new, secondary position.  Then adjust the visibility of each copy on different Scenes by putting the copies on different Layers (and changing Layer visibility) or simply hiding the groups you don't want to see on specific Scenes.  Be sure to refresh the Scene each time a Scene change is made.  Note the custom keyboard shortcut created for Paste In Place in the image, Ctrl+Shift+V in the image.

Don't forget to save (or refresh) Scenes with each change, like changes in Layer visibility or camera position.

    • Animate Sections  CMD - This plugin automates the process of applying animating sections to groups. 
    • DoorsSK  Сергей К. - Create and manipulate doors opening and closing.
    • Eneroth Cut Surface Organizer  Eneroth - Places cut geometry on its own layer so it can be hidden when the model as a whole is shown.
    • Create Section Drawing  tak2hata - Export Sections as drawings in SKP and DXF format with Entity Info annotated to drawings.
    • Section By Camera  pgarmyn - Creates realistic internal shadows when section cuts are active from a plan or section view.
    • SectionCutFace.rb  The script makes a face at the section cut.  Alternatively, paint the backface an unobtrusive color to 'disguise' the backface.
    • Super Section  Clark B - Places an existing section cut on its own layer and it's own scene, and aligns the view.
 


Flyby Animation

Post-processing in an animation program (Camtasia Studio, for example) can adjust animation speeds of select scenes or try some of the plugins listed below.
