Sprite Packer doesn't work.

I have opened the sprite packer in the editor settings, and give the packing tag of my sprite. But when i click the pack button of sprite packer window, nothing happened.


I try to create a new project to do this, and it works.

Is there any way to fix the problem of my old project ?

 

Go in to Project Settings > Editor and make sure Sprite Packer is set to Always Enabled.

 

Yes, it is always enabled, and i can see the pack button.

But when i clicked the pack button, nothing happened. I already set the packing tag.

 

I found the answer to this in another thread. For some reason you have to disable it first and then re-enable it again to make packing work. Not sure what is up with that.

 

I have tried this, It only works on new Project.

 

I'm having same trouble.
I've checked every sprites packing tag, Project Settings > Editor and Sprite Packer is Always Enabled checked.

It works on new project though, like apache_cd said.
I tried it on an empty project with exact same resources and it works properly.
Anyone having same trouble like this, please share your experience.

 

That's why its under Developer Preview... Report for bug.. see here how to do it
http://unity3d.com/BugReportingFAQ

 

It's JULY, and it still does not work

 

Can you send a bug report with the project in which packing doesn't work?

 

No, because its JULY and it SHOULD work ALREADY ...

right..?

 

It has always worked, that's why I want you to prove me wrong

 

Same issue here. Sprite Packer mode is set to Always Enabled, sprites have packing tags, but Window/Sprite Packer shows and does nothing. Using Unity 4.6.0b20

 

Check that the sprites you are trying to pack are not located inside a Resources subfolder. Per this thread http://forum.unity3d.com/threads/un...t-pack-images-inside-resources-folder.248349/, that doesn't work.

 

Thanks for the link. That explains it for my case. I don't remember anything saying in the Unity manual that sprite packing won't work in Resources folder.

 

Nope. Had to learn it the hard way

 

Still doesn't work here ^^ (unity 5.1.2f1). i've tried multiple workarounds, the Sprite packer window is still empty (and packing don't happen at all, infact there are actually 3 drawcalls by drawing all the tiles :/)

Here's scene reproducin the problem (on my machine at least) ^^.

tiles are just test graphics stolen, don't use them

I have just downloaded and installed unity personal edition

 

I ended up using my own packer I wrote before unity 5 in the meanwhile.. anyway wasn't the packer 1 of the major features?

 

I had the same problem. Moving the sprites to a folder outside the Resources folder worked for me, thanks for the tip!

 

Thnx TimK_personal!

 

I had to do this steps:

1. Move the assets outside the resource folder.
2. Disable and re-enable the sprite packer from the Project Settings > Editor
3. Close the project and reopen it

 

I'm having the exact same problem, on 5.3 and none of the above works. What gives (works in new project, btw)?

 

Same here, but for me it creates the atlas with 1 of the sprites that are supposed to be in it. I'm on unity 5.3.3p3.

 

Found my issue, looks like if you have Read/Write Enabled in import settings those sprites won't be included in an atlas. Not sure if that's by design.

 

Cool, thanks for letting us know.

 

I had to do all of this, and then change the PackingTag

(ex. Packing tag was "L1". I typed "L0", then typed "L1" again, and hit APPLY)

Then it worked!

Thanks!

 

Hi all,
I was having a similar issue when trying to sprite pack. What fixed it for me was toggling sprite mode from Multiple to Single in the inspector.

 

Do all sprites have to be in the same folder? Or is it a bug where sprites from different folders will not be packed?
half my sprites are not being packed.. I started moving them around into different folders and it started packing..

 

I also don't see any result with the SpritePacker, it's enabled, there are packing tags, but it does nothing, I don't get it. My images are in Assets/Images/Elements, they're pngs
This seems like a MAIN feature, should definitely work!
Unity 5.5.0f3 64 bits

 

TexturePacker (www.codeandweb.com/texturepacker)

 

Make sure the sprites are not in the Resources folder.
I couldn't get it to work as well. Pulling hairs out, doing tutorials again and again. The tutorials were working, but inside my project not.
Then I moved my textures out of the Resources folder and it works in my project now.
Who knows why is that?

 

I can't find the Resources folder. I'm using Unity 2017.

 

Okay, I double-checked, and the sprites I'm trying to pack are NOT in the resource folder. I am using the personal edition. Does anyone have suggestions?

 

Unity 2017.1.1f1

• Check resource folder - I have
• Disable/Enable/Reopen - done
• Use external such as TexturePacker - done

Anything I'm missing?

 

Just spent an hour trying to sort this out.

It was because I didn't restart the project after moving the sprites.

I think we need some work on this 'packer' window, as it seems rather dodgy and under developed.

Firstly with the hidden requirement that it they cant be in the resources folder, and that after moving them you have to restart your project.

 

TY for that, the warning in unity console just said 'project > editor' and that had me looking everywhere.
Maybe they can change that for those with exacting needs <wink>

 

Have same issue. (2019.2.9f1 not builds atlases and some atlases corrupted)
It's starts for me when I closed window with atlas building during atlas building.
I've tried to fix by deleting AtlasCache in Library - There was an one time atlas build started, but then some atlases still corrupted in game.

 

HOW I SOLVED THIS ISSUE

Select those sprites you want to add in the Atlas and check on Inspector if they have Texture Type as Sprite 2D and UI.

for some reason It doesn't work if the sprites are default

 

Same issue in 2019.2.15f

Switching all sprites to Sprite 2D and UI AND changing all max sizes to 2056 did the trick.

Seems like there should be an error message when you press the button and it fails. We also were having weird artifacts in our scenes of sprites being on top of each other in the atlas.

 

I have the same problem. Nothing works for me.
