Unity 3.6 SkeletonGraphic multiple texture atlases

r0bbyboy

Messing around with the new UI SkeletonGrarphic added in 3.6 we’re noticing that it does not handle skeletons made up of multiple texture atlases. Attachments seem to use the correct coordinates but always map those coordinates to the first texture atlas in the list resulting in the wrong images on certain body parts.

See example in screenshot.

Pharan

SkeletonGraphic can't handle multiple textures because its base class, UnityEngine.UI.MaskableGraphic can't handle multiple textures.

We use that class to properly incorporate it into the UI system.

Is having a larger atlas size not an option for you?

in some cases yes but with our player characters that have lots of customization options no. It is ok we already created render texture workaround when we were using 3.5.

Hi,

I am a novice currently trying to place a spine NPC on top of unity UI canvas image.

Apparently having a lot of attachments for each slot count as having more textures according to SkeletonGraphic. Please see the monstrosity of a NPC using skeleton graphic here: https://imgur.com/a/rFtJUnS.

I have read somewhere that one way to work around this is using SkeletonAnimation with screen space camera, which yield this result of the skeleton "collapsing" into blobs: https://imgur.com/a/jsCYrzu

Can you explain step by step in a very explicit way how to either:

1) properly incorporate SkeletonAnimation with Screen Space Camera to display character in canvas (I see no step-by-step beginner friendly guide to this anywhere on google?)

2) Explain in detail how a larger atlas size should be able to solve this, according to the Pharan post above?

3) @r0bbyboy how did you in detail work around this? The lack of beginner friendly documentation on implementation is frustrating. 🙁

Best regards,

Raeiraei

edit: closest thing i could find on this was Spine animations in Unity GUI?, but that does not seem to do the trick (no idea what to assign to repacked shader).

edit2: sadly this link has gone 404 - http://esotericsoftware.com/files/runtimes/unity/spine-unity-experimental-SkeletonGraphicMultiObject.unitypackage

where is the proper noob friendly implementation documentation??? 😃 🙁

edit3: for all the other beginners out there

you can use a seperate canvas, set to 'screen space camera'. In this case it has the main camera assigned. Sorting order set to something below the spine object. Then use regular spine animation with a higher sorting layer in front.
