Spine 2d object missing/error material in Unity 6

toptomsk

When I upgrade unity vertion to 6000, all my asset bundles contain spine animation are broken like the images below. Is anyone having this error like me?
If object are in scene (not in asset bundle i download from server), it's showing like normal, but for asset bundle it''s not.

It seems like you are encountering an issue with Spine animations in Unity 6, specifically when using asset bundles. This problem might be related to the compatibility of the spine-unity runtime with Unity 6. The spine-unity 4.2 packages have been updated to be compatible with Unity 6, so ensuring you have the latest version of the spine-unity runtime could potentially resolve the issue. Additionally, if you have switched from the Built-In Render Pipeline to URP, make sure that your materials and shaders are correctly set up for URP. If the problem persists, it might be helpful to check if there are any errors in the console that could provide more insight into the issue.

Spinebot But my spine animations were export by Spine version 3.7.94, for now we can not re-export theme to match version 4.2 as suggest, so we only use Spine Runtime 3.7

toptomsk The Unity Editor versions supported by spine-unity runtime 3.7 are Unity 5.6-2018.4. Please use a supported version of the Unity Editor.
If you would prefer to use Unity 6, re-export your skeletons with Spine 4.2, then install spine-unity Runtime 4.2 into your Unity project.

@toptomsk If you are unsure which version of the spine-unity runtime and UPM packages support which Unity version, they are listed on the spine-unity download page:
