I have a few Fade In animations on some PowerPoint slides that, when I import into Captivate the objects with the animation either are already on the slide or they are not and there is just an empty space where the object should fade in to. Do you recommend not using animations in PowerPoint when importing into Captivate 7 or is there a trick to getting the animations to work?
Animations created in PPT slides do not really get preserved in any useful format once you pull the PPT deck into Captivate.
Experienced Captivate authors will generally try to discourage you from bothering about building your course content initially in PPT because it imposes too many limitations on what you can achieve.
I realise that you may be given an existing PPT by some client or SME and asked to turn it into a Captivate project. If you want the best possible results, accept the PPT graciously, and then rebuild the thing in Captivate from the ground up, using the PPT deck as a reference point only.
