Thank for interested in Cloud Animator, and watching our tutorials, and webinar.
For your question, we would like to inquire you that which OS(window's PC/ IOS) do you use? Because the IOS security browser issue, it not allow the 3rd party to save the date to user's browser cache. So the CTA3's feature, "Capture for Cloud Animator", now is available for the windows PC platform only.
So if you are the Macitosh user, you still can apply the Render>Render Image，and then select one of the formats (JPG/ PNG/ BMP/ GIF/ TGA) you prefer. But just kindly remind you, Cloud Animator supports JPG/ PNG/ SVG/ GIF now.
If you need more info for the Cloud Animator, you may go to our website:https://www.reallusion.com/cloudanimator/getting_start.html
Thanks again, and have a nice day.
