Hello,

We are updating to spine 3.8 - was the Ragdoll and the Kinematics Shadow Modules removed from the integration completely?
Got error in scripts using those two, since they no longer exist. Is there a substitute in the pkg?

It seems their namespace has been changed, see the notes on SkeletonRagdoll2D etc. in the CHANGELOG spine-runtimes/CHANGELOG.md at 3.8

Finally upgraded to Spine 3.8! Aside from fixing the changed method/variable names, it went pretty smoothly. Only one issue spotted so far and it's related to Attachment's "GetRemappedClone". On Spine 3.7, region attachments would copy any color tinting, but mesh attachments wouldn't. So I had code like this:

Spine.Attachment newAttachment = templateAttachment.GetRemappedClone(atlasRegion, true, true, skeletonDataAsset.scale);
 if (newAttachment == null)
     Debug.Log("clone attachment failed for " + originalSkin + " " + regionName + " " + slot + " " + templateAttachmentName);
 if (templateAttachment.GetType() == typeof(Spine.MeshAttachment))
 {
     Spine.MeshAttachment newAttachmentCasted = (Spine.MeshAttachment)newAttachment;
     Spine.MeshAttachment oldAttachment = (Spine.MeshAttachment)templateAttachment;
     newAttachmentCasted.R = oldAttachment.R;
     newAttachmentCasted.G = oldAttachment.G;
     newAttachmentCasted.B = oldAttachment.B;
     newAttachmentCasted.A = oldAttachment.A;
 }

But I noticed in Spine 3.8, a bunch of our attachments were appearing white suddenly. So it turns out we need to also do this check for RegionAttachments now:

if (templateAttachment.GetType() == typeof(Spine.MeshAttachment))
        {
            Spine.MeshAttachment newAttachmentCasted = (Spine.MeshAttachment)newAttachment;
            Spine.MeshAttachment oldAttachment = (Spine.MeshAttachment)templateAttachment;
            newAttachmentCasted.R = oldAttachment.R;
            newAttachmentCasted.G = oldAttachment.G;
            newAttachmentCasted.B = oldAttachment.B;
            newAttachmentCasted.A = oldAttachment.A;
        }
        else if (templateAttachment.GetType() == typeof(Spine.RegionAttachment))
        {
            Spine.RegionAttachment newAttachmentCasted = (Spine.RegionAttachment)newAttachment;
            Spine.RegionAttachment oldAttachment = (Spine.RegionAttachment)templateAttachment;
            newAttachmentCasted.R = oldAttachment.R;
            newAttachmentCasted.G = oldAttachment.G;
            newAttachmentCasted.B = oldAttachment.B;
            newAttachmentCasted.A = oldAttachment.A;
        }

I'm not sure if this is intended but it's something I came across.

I'm having trouble getting the timeline package to work. I've installed the spine 3.8 UPM and fixed all compile errors related to that (we are upgrading from 3.7). But when bringing in the timeline package (I can't find a UPM, only a zip) I'm getting new errors stating that various spine namespaces can't be found. Could I be installing it incorrectly? I just unzipped the archive to the packages folder in my unity project. I tried importing the zip with the package importer, but it gives me an error that states that all of the files already exist in my project (they don't).

Any thoughts?

I'm also seeing an issue with certain meshes not displaying properly for re-exported skeleton files; it seems that some weighted meshes appear to have negative scaling or are skewed or something, although there is nothing on the bone rotation/scaling to suggest why this would be happening. Any help would be greatly appreciated.

Unity version is 2019.4.9f1

Please note that our resident Unity expert, Harald, is currently on vacation. He'll catch up to forum posts and everything else ASAP when he's back. I can try to help, but I apologize if only in a basic way.

There should not be any errors after installing, so that is a clue something went wrong early on. Did you get spine-unity from the download page? You should remove the old files first, otherwise you could have a mix of old and new files which would cause problems.

Thanks Nate, any help is appreciated. I completely removed all spine files and reinstalled (the spine-unity upm and timeline package are both from the downloads page). In the process of reinstalling, I've noticed that the namespace compile errors are only popping up when 'SPINE_TK2D' is defined. As soon as it's disabled, they disappear. Could there be a compatibility issue with the timeline package and tk2d support? Hopefully that helps to narrow it down.

Oy, it very well could be an issue with Toolkit2D. It is not as popular as using straight Unity, so likely sees less testing. I'm afraid this is Harald's domain, we may need to wait for him to return.

Thank you so much, it looks like I can export the 3.8 version files using 4.0 (as 3.8 does not have versioned exports that I can find) and import without issue to 3.7. I think she updated recently, thankfully, but I have requested she set her projects to 3.7 so we won't have any further issues.
