  • Solve Tangents not working

I'm having an issue with Solve Tangents. Your example scene is working fine, but when I apply Solve Tangents to my own sprite I have issues. If I override the sprite's motion with SkeletonUtility, the tangents appear to solve. But if I run an animation, the tangents appear static.

See the following image for details. I am debugging worldNormals to show the issue. The attached issue is in my homebrewed shader, but the same issue appears if I try to apply your out-of-the-box shaders.

Sorry, I didn't notice this thread!

We'll check this problem out.

Are you on Spine 3.6 or on 3.7?

No problem! Let me know what I can share with you to help this go smoothly!

I believe 3.6. The runtime in unity says "This runtime works with data exported from Spine Editor version: 3.6.xx" ... can't find any other versioning info. Should we attempt an upgrade?

No, but if you haven't done so recently, update it using the latest 3.6 unitypackage.

There was a bugfix earlier this year (still 3.6) that fixed a problem with tangents not being updated.

Updated. Same issue currently. I may be willing to make a simple example scene to send your way, if you're interested.

Pharan, you should have just received a Google Drive link from me to share a sample project. Let me know your thoughts, or if you have any questions about my process.

One small additional bug: if you make the camera orthographic (ortho size 7) in that scene, the z-sort order of the slots gets all messed up.

I can confirm that we've received the email but I can't seem to access the folder.

Regarding the sort order, if you're not using a depth-reading/writing shader, is your problem similar to the problem in this thread?

What does it say when you try to access? Make sure at the top right of your Google drive page that you are accessing as unity@esotericsoftware.com ... Or if that's an alias, please give me the email address you are using.

Thank you. I sent it to the new address. I also added sorting groups, and it worked. Thank you, Pharan!

I'm sure this is clear, but just in case: sorting groups fixed the orthographic camera issue. Tangents are still wrong in animation.

Thanks, we've received the repro case.

I think I found the problem. Just something weird with submesh counts we're doing. It only manifested when the renderer uses multiple submeshes.
I'll push a fix soon. Stay tuned.

Thank you! I think we would prefer to be using one mesh, I just had some issues when I tried to bake my skin at runtime. I probably need to take another look at that.

Can you try the latest unitypackage now? It should be dated today (November 15)

There were a few additional related bugs that I ran into that should have been fixed in the process.
Let us know if you run into any problems with the runtime!
