PSD Importer 1.2.0 Not Creating Sprite Library/Resolvers

I've been trying out PSD Importer 1.2.0 with Unity 2019.2.6f1 Personal and have really been appreciating the easy splitting of the different layers into a single prefab.

One feature I was interested in as mentioned here: https://docs.unity3d.com/Packages/com.unity.2d.animation@3.0/manual/SSManual.html is the PSD Importer automatically creating a sprite library and adding a Sprite Resolver to each object for easy sprite swapping during the game. The use case we're looking at is swapping clothing and visual items on a character.

While I've been able to get the Prefab with the split components when importing the PSB file, one thing I haven't been able to get working was the automatic sprite library/resolver creation. Each object just has a normal sprite renderer and we're having to go to each sprite to manually build the sprite library asset, and add sprite library components and add resolvers, etc to each object. Looking through https://docs.unity3d.com/Packages/c...r@1.2/manual/index.html#name-collision-errors I didn't see any config options that would control this.

How do I get the PSD importer to handle the auto-creation of sprite libraries and sprite resolvers for PSBs imported using PSD importer?

 

Previously I had been using 2.20-preview.2

I installed Unity 2019.3.0b7, and confirmed I now had 2D Animation 3.0.5, and 2D PDF Importer 2.0.5.

I freshly imported the PSB file, and the result was the same as previously; a prefab with the layers split into objects, each only with a Sprite Render component with the specific sprite. No Sprite Library Assets were created, nor was any Sprite Library Components or Sprite Resolver components.

I did see numerous warnings in the console on import:
"File's Layer ID is not unique. Please report to developer. 0 PLAYER SELECT::SQUARE SELECT
UnityEditor.Experimental.AssetImporters.ScriptedImporter:GenerateAssetData(AssetImportContext)"
"File's Layer ID is not unique. Please report to developer. 0 Buttons::Remaining Boxing for Layout
UnityEditor.Experimental.AssetImporters.ScriptedImporter:GenerateAssetData(AssetImportContext)"
"File's Layer ID is not unique. Please report to developer. 0 Remaining Boxing for Layout::SINGLE INVENTORY BOX
UnityEditor.Experimental.AssetImporters.ScriptedImporter:GenerateAssetData(AssetImportContext)"
etc


Could the lack of Sprite Libraries/Resolvers be a function of some aspect of the PSB file?

 

Thanks for the info! After reading your post, I did some more Googling and found https://docs.unity3d.com/Packages/com.unity.2d.animation@2.2/manual/EditInter.html

The PSB importer I had imported originally only showed me the "Bone" category and not a "Sprite" category, so I re-imported the PSB, went straight to the Sprite Editor and then the Skinning Editor, and now my Sprites are listed once I opened the Visibility tab. I was able to assign Categories and Labels and confirm that the Sprite Library/Resolver Assets and Components were being created. Thank you so much!

 

Thanks for that. Today, the doc doesn't mention using the Skinning Editor to create the library, or maybe it's hidden somewhere? Sigh...

 

Hi @Ted_Wikman and thank you for the long answer!

I'm currently using 2020.3.3f1 and the 2D Animation package is up to date, version 5.0.4.

It appears that using the Skinning Editor does the trick and does it very easily.

(Note: In case people would wonder where this Skinning Editor is, it's in the Sprite Editor, at the bottom of the drop down list on the left.)

There is a Visibility panel on the right, there you can assign categories and labels to each sprite in a very easy way, just right-click on the sprite in the list and select "Convert Layer to Category". There also, you can organise and name your bones. (This visibility panel no longer exists in Unity 2021, as @Ted_Wikman already mentioned.)

​

Do that for every sprite in the list, apply and then:

• the Sprite Library component will be added to the character,
• the Sprite Library asset will be created inside the character prefab,
  
• all the Sprite Resolvers will be created.

​

I hope this will be helpful.

 

You're welcome!

I'm about to update the project to 2020.3.4f1. Things should go well but I'll come back here if needed.

 

I upgraded to 2020.3.4f1, no apparent problem. Except that I cannot find Collections in the Package Manager, even in the preview packages.

In the meantime, Collections being installed in another project of yours, I just copied:

    "com.unity.collections": "0.15.0-preview.21",

into my project packages manifest and it was installed but why isn't it available in the list?

Thanks.

I tried to switch from 2020 to 2021 because the sprite swapping with the .psb was quite buggy when I reimported a newer version of the .psb file.

I understand, that there now is only one way to setup the sprite swap, but the automatically generated sprite library had one big advantage and I cant find a way to achieve something similar in 2D Animation 6.5

In the older version, when I configured the categories and Labels in the skinning editor, the generated prefab had only one gameobject for every category, which makes absolutely sense. Now in the newer version, i have a child for every sprite, which means I have several gameobjects that I don't want to use and I cant remove them because it is an automatically generated prefab.

The only way I see, to achieve this is to have two psb files. One that has only one sprite per body part and one that has all the sprites, which i can make the sprite library from.

Am I missing something? How would you achieve this?

 

In version 5.x I discovered multiple problems, that appeared when I updated the .psb (by simply exchanging it in the folder outside of unity) for example when some objects of the .psb moved in the hierarchy or where taken out.
It resulted in some labels beeing somehow occupied because it seemed to still keep some reference to old objects and said there is another sprite with that label, but there wasnt. Also some layers/sprites did not appear in the skinning editor but then still appeared as a seperated gameobject in the generated prefab. The only way to fix these things was to delete the .meta file and make the whole skinning new.

Of course I could do that, but I like to have my prefabs cleaned up, and not full of inactive gameobjects that I never use.

 

I just found a solution that fixes my problems in version 5.x

Edit: I was wrong, some problems still remain. Here is what I thought would help maybe its helpful for someone else:

I can reset all categories by doing the following:

• select all Groups and layers in the skinning editor
• right click > Clear All Category
  
• click on the category dropdown of a layer > Remove Empty Category
• click apply (don't know it this is necessary)
  
• create the categories new (in my case by selecting all groups and right clicking > Convert Group To Category)
  
• click apply

 

So after doing this, here is what remains: when I move a layer above another, it is not possible to "Remove Empty Category". this leads to having occupied labels and the generated gameobject does not have a sprite for this category.

But! I found a solution:

If I do "Clear All Category" and "Remove Empty Category" before updating the psb I have all Categories cleared and can then create new ones afterwards.

 

Thank you, I indeed didn't have the newest version after reverting tu 2020.3. I am at 5.0.4 right now. I will update now and will open a bug report in case that the error persists
