How many animation can I have running in 1 scene on mobile?

Hi, I am experimenting with Spine for sometime and now consider buying it. However I ran into some problem and wanted to make sure that Spine is the right solution before making purchase.

I'm creating a mobile game in which there could be 200+ spine animation running in 1 scene. I see a serious performance issue on iPhone 4 when there is 200+ animations. It runs fine if less than 150.

I want to know if 200+ animations is achievable with Spine? If not then what should be the most number of animation I can have roughly running on mobile (minimum iPhone 4)?

I'm developing on Unity so I'm using Spine unity runtime. One weird thing though, Spine 2dtoolkit runtime seems to have a performance issue compared to Spine unity runtime. It slowing down with only 100+ animations on iPhone 4.
Thanks.

It's difficult to say exactly how many animations you can have running. It depends a lot on the amount of bones you have in your characters. So I can't give you a rough estimate on how many you can have running on mobile.
Keep in mind that you can also export animations done in spine as regular sprite based animations and you might want to use both for scenes where you have a lot of characters. Without knowing what kind of game you're doing it is of course hard to say if this will be an option for you.

I highly recommend this video http://www.youtube.com/watch?v=dcmk_bXxRHo btw.

Like most things, it depends on a lot of factors. It takes CPU to compute bone positions, so with many many bones and many skeleton instances, you could be CPU bound. Much more likely though, on mobile you will be fill rate limited. Then it depends on how many pixels you are drawing, ie big your images are and how many images you use per skeleton instance.
