Glass patterns in Builder?

Hi all,
I’m using PsychoPy3 on a Mac computer (OS Catalina). I ‘inherited’ an experiment on MATLAB that I’d like to recode in Psychopy. The stimuli are glass patterns (Glass 1969), which are similar to random dot patterns. Is there any way to create glass pattern stimuli using the builder? Or should I figure out how to export the stimuli from MATLAB (as video files?) and then upload those to the Builder?
I’m a newbie and not great at programming… so any help is much appreciated :slight_smile: Thank you!
