Sprite/Texture Packer, Unity v5 ?

Is there a built in Texture Atlas Builder in Unity v5? I see sprite packer, but not clear how it's used. Doc's seem a bit vague. Or, do I need to use 2D toolkit for this?

 

You're in the right neighbourhood

Sprite Packer is the atlas/sprite sheet builder, but choosing where sprites go is done in each image's inspector, via Packing Tag. You can select all the sprites you want to put into one sheet and give them the same tag, then the Pack button in the packer window will assemble as many sheets as it thinks is necessary.

The Sprite Editor button on each image lets you slice existing sheets automatically or as a grid, and change the pivot point on individual sprites.

 

So, I filled in the Packing Tag, now what? Nothing else happens and I cannot drag my sprites into the Sprite Packer. Clicking "Pack" does nothing -- are you missing a step? Are there official instructions somewhere? Maybe a Youtube?

 

There's no dragging involved. If it has made atlases, you should see them in the packer window. The only steps are to have sprites, tag them and pack.

 

How can I tell if it worked? PS. I'm using the Personal Edition, if that matters?

 

If it worked there should be atlases showing in the Sprite Packer window

 

There aren't. But I don't know what it wouldn't work. Seems either that it's not supported in the Personal Edition or a Bug.

 

8 images, import Texture Type: Sprite (2D and UI), Sprite Mode: Single, Packing Tag: Test, Pixels Per Unit: 1, Pivot: Center, Generate Mip Maps (unchecked), Filter Mode: Point, Max Size: 8192 (changed from 1024 to see if mattered, doesn't), Format: True Color.

I clicked PACK in the Sprite Packer and clicked PLAY. Draw calls are still what they were before I attempted to Pack. Looking at Sprite Packer during and after run, nothing there.

 

Check that it's actually enabled too: http://docs.unity3d.com/Manual/SpritePacker.html

 

Always Enabled is what is selected (has been selected, didn't need to change)

 

The max size only affects the maximum size the imported image should have. It's useful for different sizes if you have a mobile+desktop project.

 

Dunno what the problem could be then :/

 

Doesn't work.

 

Exactly the same with me... Wanted to try the Sprite Packer, enabled it, gave my sprites a tag but nothing is appearing in the Sprite Packer window, the "Pack" button does nothing... Hope someone can tell what we're doing wrong

 

Same here. Sprite Packing is Always Enabled, Packing tags are set, and if I tell it to Pack in the Sprite Packer window it processes something for a while. But nothing shows up in the Sprite Packer window when it's done. The atlas drop down is blank and I don't see any atlas folder under the library folder.

 

Right now, I've tested Sprite packer with Unity Pro and Unity Personal, It is working.

 

An update...

If I take the same content, start a new project and use the same settings, all the atlas functionality works. Which leads me to believe some third party element in my project is preventing it from working. My money is on EZGui as that is the UI framework that has clashed with the naming conventions in the new UI.

I'm going to do a bit more research.
