Skeleton data/sprite scaling mismatch with Unity

Lion Christ

Hello. This is my first post here, and I am attempting my first importing of Spine animations into Unity. However, when I have the scaling for the skeleton data to be "1", the sprite is HUGE when placed into the scene. I mean enormous. My character is about 256 pixels tall from a photoshop file that is 2048x2048. It is exported from spine with a scaling set for 1 and a max width and height of 2048 in the "pages" part of pack settings during export. However, when the skeleton data (also at a scaling of 1) is placed into scene, the sprite is roughly 32,400 pixels tall. It is the height of fifteen 4k png images. I realize I can dial the scaling down to .0025-.01, but I would prefer to know why this is happening so that I do not run into additional problems down the line, possibly with things such as UI. Thanks to anyone who can help!

Scale of 1 typically will match one pixel to one unit (unless you scaled the attachment images in Spine).

Please see the spine-unity documentation section here:
spine-unity Runtime Documentation: Skeleton Data

Very helpful, thank you!

For anyone else that encounters character scaling issues, and comes across this thread in the future:

First: Check your Skeleton Data's "scale" amount. I exported different animations with the same settings from Spine, yet somehow, the resulting Skeleton Datas had different default scales.

Second: When you change the Skeleton Data scale, you don't simply enter a new value into the field. For the new scale value to take effect, you must PRESS ENTER, then drag the skeleton data into the hierarchy again to create a new skeleton animation.

hamcha Sorry to hear you were having troubles with Skeleton Data scale. Unfortunately, we could not reproduce this issue on 4.2 or 4.3-beta: the scene skeletons were updated immediately after changing the SkeletonDataAsset scale. Also it updated not only after hitting Enter, but also by clicking anywhere else, using Tab, or any other means of committing the field changes, even when using slider-editing to gradually increase or decrease scale. Which exact version of the spine-unity runtime (name of the unitypackage, also listed in Assets/Spine/version.txt, or in the Package Manager window) are you using?

In general whenever a skeleton instance in the scene does not reflect any SkeletonData changes, you could also hit Reload at the SkeletonRenderer (SkeletonAnimation) component instead of dragging and dropping the skeleton to the scene again to create an instance. Also whenever a scene is reloaded, any SkeletonDataAsset changes are automatically reflected.

hamcha First: Check your Skeleton Data's "scale" amount. I exported different animations with the same settings from Spine, yet somehow, the resulting Skeleton Datas had different default scales.

The default SkeletonData Asset scale is set via the Edit - Preferences - Spine setting Default SkeletonData Scale under Auto Import Settingsin Unity. If you change this value, it will apply it at subsequent skeleton imports.

Thanks for checking this, Harald!
I use Unity 2020.3.8f1, which might be the cuase of those wonky issues specific to me.
The Default SkeletonData Scale is really good to know about!
