Hi,
I've been testing the spine mix and match flow with the Unity runtime and i'm wondering if it is possible to use already-unity-packed sprites with Option 2 described here (Option 2: Use template attachments in Spine, and generate Attachments from UnityEngine.Sprites in Unity. http://en.esotericsoftware.com/spine-unity-mix-and-match)

Using already-packed sprites would be nice to avoid the Runtime Repacking if possible. I'm imagining a draw order where it draws from the packed atlas for the equipped item, and draws from the main texture for the rest of the character.

A quick test by modifying the Mix and Match Equip example scene does not seem to work - but maybe i'm missing something!

Here's what I did

1. Start with the Mix and Match Equip example scene
2. Create a unity Sprite Atlas asset containing the Spine Examples/SpineSkeletons/spineboy-unity/Equips/ "goggles-normal" "goggles-tactical" "gun-freeze" and "gun-normal"
3. Set the import settings on those sprites to be "Full Rect" and "Read/Write"
4. Uncheck the pre-multiplied alpha flag on the EquipSystemExample script so that it no longer creates temporary textures when calling attachment.GetRemappedClone(...)

If i'm understanding the documentation, this should render the existing sprite but I just see a white polygon when equipping it.

Anyone have thoughts? thanks!

Thanks for the thoughts! compression = none is a good catch, but it still renders as a white box when rendering from a sprite atlased asset (see image)

Not sure if this is an expected use case. If it did work, it would be an interesting compromise between using the temporary textures for rendering and a full runtime bake
