Hello,

I have used CC animation in the past to show a virtual flythrough of a PC and it worked very well. I am trying to create a type of animation through time, where I take a viewpoint of data collected on one day and then hide that PC layer, show a more recent PC layer, take a view point and would like to continue that progression through multiple PCs. When I try, I seem to take the same viewpoint regardless of the hidden or shown PC layers.

Should I be able to do this in CC? Am I just setting up the viewpoints incorrectly?

Hi,

Viewports, are really only a way to save the position of the OpenGL camera. They are not linked to any entity (visibility). They are independent on the contents of the database.

I fear what you are trying to do won't work with viewports. You would need a different kind of object (that would retain the visibility of specific entities).

Ah, that's probably because viewpoints and entities are totally independent (the visibility of entities is not saved in viewport entities).

You should probably generate a nice screen capture (Display > Render to file) of each PC, and then use another tool to generate a video from these still images...
