I've been searching for an answer to this but I can't seem to find a clear yes or no if this is supported.

It seems like a feature that's supported and it works perfectly fine in the Spine Editor, but when it comes to implementing it into the engine, it crashes on build.

I have a character with a few strands of hair, the hair is built with long meshes with a few bones rigged to each strand. I made an image sequence of the lock of hair with a highlight that sweeps along the length of the hair.

The character imports fine if the hair is using a static PNG texture but as soon as I make it an image sequence with the highlight that animates, the game won't build and crashes when trying to load Mesh Attachment Hair_Sequence.

I've done a few tests:
Rigged Mesh Hair with a static texture works.
Image plane with the animated hair sequence works.
Image plane attached to a bone with animated hair sequence works.
Rigged Mesh Hair with the image sequence as a texture fails.

Alright, I'll let IT know and hopefully that fixes the issue.

Thanks Nate

@Nate I am running spine.com and it hangs for a second before returning to the command line.

The only type of protection installed is SentinelOne, which I'm unfortunately unable to disable or interact with without IT intervention. I can get in touch with IT to see if they can temporarily disable it and see if that fixes the issue.

I was able to find an older installer for version 3.8.99 and it installs and opens just fine with this version. Any idea why this one works but newer versions won't?

Our company has Spine Professional licenses, if I install this older version, are we able to update to the latest version with our license?

Hi, I'm currently experience a similar issue with Spine not opening. My company has pivoted to employees working from home and I'm unable to get Spine working on my home PC. I've installed, reinstalled, and even tried installing the Spine trial just in case. None of them want to launch. The installer version I'm using is 4.0.23.

There are no spine.log files being created and when I try launching it through Command Prompt it also doesn't report any activity. It seems like nothing is happening at all no matter which method I use to open Spine.

I am running a multi monitor setup and I've tried restarting using only one monitor still to no avail.

I followed as much of the trouble shooting as I could above, I ran all of the java OpenGL tests 1 through 8 mentioned above and didn't get any errors. All of the tests were able to open the green window.

Are there any other suggestions or troubleshooting help I can follow?

My PC specs are:
AMD Ryzen 9 3950X
Nvidia RTX 3080
Two 3440x1440 ultrawide monitors and a single 4k 3840x2160 monitor
