Question by hulahoolgames · Aug 28, 2015 at 06:48 PM · spritesartifactssprite packer

Sprites are stretched after packing with sprite packer

I am using Unity 5.1.0 Personal edition. I am seeing some artifacts after packing my sprites using Unity's Sprite Packer. Here are two screenshots that show the artifacts in my sprites. Lot of space is being wasted in the atlas and more sprites can be packed in the remaining space. Let me know if anyone else is experiencing this issue and has a solution for it. Thanks in advance for all the help.alt textalt text

Hello,

I'm also facing the same problem, but it didn't effect my games ( or sprites I'm using), I'm assu$$anonymous$$g the same with you guys. If you are thinking that the empty space is wasting then tag more sprites so they should also come in this sprite sheet .. OR Can you please tell that How it is effecting you game ? :)

Thanks

@itsharshdeep the only way its affecting my game is in the number of batch calls. I guess I will have to group more things a bit intelligently to bring them down. Will try that and send out an update here. Thanks for your suggestion.

I believe I figured it out. I was importing a Multiple Sprite into the atlas. But instead of slicing by grid size - I sliced Automatically. As soon as I sliced by grid size (effectively keeping all sprites to the same size - the artifacts disappeared. Some threads on FB also point to Wrap Mode set to Clamp as a potential source of glitching.
