The enforced removal of the Flash Player by Adobe means that Flash .SWF files can no longer play, at least when opened with a tool that relied on the PC’s main Flash Player engine.
However this has not caused problems with Reallusion Cartoon Animator, which can still import .SWF files for conversion to props. For instance I can still drag-and-drop a Flash .SWF asset to the CrazyTalk Animator (now Cartoon Animator) stage, and have it instantly become a prop…
Possibly this is because Animator appears to have its own internal standalone Flash player, presumably for import of props and not under the control of Adobe, at least in the version I’m using (Animator 3 Pipeline)…
Tests also show that vector-capable graphics software such as PhotoLine, able to write .SWF files, are still able to do so.
