¡HOLA!

Yes, you can achieve this by organizing your Photoshop layers and using specific naming conventions. When exporting from Photoshop to Spine, you can use the [skin] tag to define the skin name and the layer name for the attachment. However, the skin placeholder name is typically derived from the layer name. To have different names for the skin placeholder and the attachment, you can manually adjust the names in Spine after importing.

For example, you can use a naming convention like [skin:CustomSkin] CustomAttachment in Photoshop. After importing into Spine, you can rename the skin placeholder to your desired name, such as CustomName, while keeping the attachment name as CustomAttachment.

This approach allows you to have different names for skin placeholders and attachments, but it requires some manual adjustments in Spine after the import.

The PSD import available from Spine 4.2 is explained in detail in the user guide, so please refer to it:

When we made the import PSD feature, we discussed internally about the possibility of introducing a tag dedicated to placeholders. Right now the rule is:

Placeholder: values of the [folder] tags from the hierarchy + the layer name.

The tag should have just replaced <layer name> with the value of the tag.

After some internal discussions, we did not add it because in most of the cases users wants the attachments and the placeholders to be coherent. Moreover, using this tag is a symptom of not ideal attachment naming.

For example, in your use case, the attachments have the Eyes_01_ information that might be considered redundant since they already belong to the Eyes_01 skin. If you remove the Eyes_01_ from your attachments, the placeholder will already have the desired name.

May I ask you why you added the skin name to the attachments? Maybe there's something in your use cases that we are not able to see.
