Question by a-t-hellboy · Feb 16, 2016 at 09:40 AM · spritemobilemobile devicesatlasmobileoptimization

Many sprites need to load on mobile devices in unity3D

My 2D game has 3 characters which each character has 7 types of animation that is contained to many frames. Those are around 1050 frames (sprites) for all 3 characters animations. I make atlas by these sprites but right now it is around 60 2048x2048 atlases with compressed format.

So on some devices which I've tested, The game is not loaded but on some other devices it is. I think it's because of too many atlases which they can't load on these mobile devices RAM.

I've tried to make these frames as small as possible and put them in atlas but as I said before the number of atlases is 60 and I can't reduce number of frames or size of them more than this.

What do you think guys and what can I do ?

I find it difficult to believe that 7 sprite animations for 3 characters take up 60 2048x2048 atlases...

Is there an example atlas you could post? This really feels excessive.

If you can afford it take a look at EsotericSoft Spine. It will look much better and reduce your atlas to one.
But yeah, I also think your frames are too big.
