Should I use 3rd party atlas packer?
Hey guys, hope you can help me solve my problem with draw calls... In my project, i used unity sprite packer, and game worked well on ios. But, on android, it seemed very laggy. So I decided to investigate performance issues, and, during the analysis, I came to really confusing issues with unity sprite packer. When I use Unity sprite packer, it seems to generate batch per different image, independently images came from different atlases or not. But when I use 3rd party packer, it works correctly, provides me 1 batch for 3 textures. So, maybe you can explain, why is this working like that? Here is the link to illustrate it: http://imgur.com/a/j8dnE
It would take me a lot of efforts to replace current UI sprites with a new one from different atlas, so maybe you can suggest something? Are there some pros and cons of using 3rd party atlas?
