Hello.
I have animation sequence with 650 png files(it one big animation). How I can load it in Defold? If I create atlas with all animation - Editor not respond anymore 
I try use PNG extention for load every png on runtime, but sometimes png after load and data read change size
How large are the individual images? You must pay attention to the final size of the atlas. Anything above 16kx16k is very likely to fail, and an atlas of that size will likely work on all graphics cards.
285х235х24 for image
Hmm, ok, that should probably pack into an 8k texture. Are you using Editor 1 or 2? If you’re using Editor 2 then please report this as an issue from Help->Report Issue.
Ok. I send report later.
Wow 650 frames… could you create a gif animation?
