Animation Preview stopped working

Romitas

Hi,
Got a trouble while using spine-unity - at some point the preview window of SkeletonData asset stopped displaying the animations previews. I can still see the animations list, click Play button, and the progress bar starts moving as if playing the animation, but nothings shows in the Preview window (doesn't work for any of the animations, skins and skeletons). There's no errors in the console, except for a Z-spacing warning which I believe has nothing to do with it (pls correct me if I'm wrong)

Skeleton itself looks correctly in editor, and in play mode everything works fine as well - the problem is only with the Preview window. spine-unity version is 4.1-2023-06-14

Please let me know if anybody maybe had a problem like this and have some idea where I might look to get it fixed. Thanks!

@Romitas Sorry to hear you're having problems with the preview! Unfortunately nothing has been changed in this regard in the codebase for quite some time. Does this only happen with your skeleton assets, or also with the example skeletons of the spine-unity runtime, located in Assets/Spine Examples/Spine Skeletons?

Is the scale perhaps off, being very small or very large? You could try scaling smaller or larger via the mouse wheel while over the Preview window section. Does anything change when you select different SkeletonDataAssets than the problematic ones and then switch back to them?

@Harald Ok, thank you!

I figured it out - turns out this had nothing to do with Spine after all, and the problem was with my material shader, which worked fine in-game, but for some reason was breaking all Unity previews, Spine included. Thank you a lot for your quick response and your help - the idea to check Spine example skeletons settings and compare them to mine was the turning point

@Romitas Very glad to hear you've figured it out! Thanks for letting us know!
