the files are checked as ‘preload’ within hype?
invoking the sequence when already running will cause this behaviour too …
could you share the document?
but as said before: Hype 4 will have a imagesequence player so you might be better of to use this built in one … as the above was never finished. i needed it for an videoexport and it’s been good enough for this …
you should definitely optimize the images (imageOptim or something simular should get about 90 % less fileweight) before placing in the resources folder and uncheck hypes image optimisation.
did you download my above we-transfer-provided file? it works for me …
Sorry, I didn’t see that. Yes, now its working.
I see that the pictures are much smaller. Is that the only thing you changed, or did you change the code (except the callback)?
please note that the images filesize can be compressed much more:
1.) using the correct size -> an imagesize that matches the size in the layout. at the moment the size is twice as needed
2.) quality for files within animation (not start or stop) can be much lower
3.) what will be the best fileformat -> png, svg, …
btw if it’s a afterEffects-export -> there’s a js-library playing those sequences which works within hype too …
so if you can get those files to after effects:
may be there’s a simular plugin + js-library for adobe character animator …
have a nice day 
Browsers need to do an image re-render when doing a set of the background image, which is the technique employed by the image sequence code. Some handle this better than others; Firefox is especially bad and likes to render the image as blank while changing. Are you previewing in Firefox?
The technique for the smoothest image sequences is to have a single image that is masked via parent group with the overflow to hidden and move its top/left position. This is how the Hype v4 sprite sheet works. I see you applied to the beta; we’ll be sending out a new batch later this week so you can test with that.
yes, ff does not draw it well. i wrote the script with purpose of a videoexport … which works fine. btw, i did a test in hype 4 throwing @schmeidt images in a spritesheet. This resulted in a 17mb file in the resources panel and did almost not play on preview -> showed blank and then finally the last frame … (chrome desktop)
btw: each pic has fullHD-size which is surely a k.o.-factor

Yeah, it is probably an issue due to the resulting spritesheet being 19,200 × 18,360 pixels. I can reproduce the problem easily on Chrome. Firefox doesn’t even show the image. Safari seems to work fine . Thanks!
Thank you @h_classen and @jonathan. Is it for performance better to work with video or png sequences?
whats the right resolution for png sequences?
smallest possible size and filesize is always recommend.
video may be a choice if you do not need transparency and interactivity.
