Getting there! If you want to send me the project I can take a look. You can DM me on twitter or on the Construct Community Discord (Mikal). I use sendgb.com to share project files usually.
Spine 4.0 beta test ongoing, you must export from Spine 4.0 (3.8 exports will not work.)
If you already have experience with Spine and the C3 plug-in, try it out. If you have not used the C3 plug-in before, I recommend staying with the current 3.8 version as the new 4.0 beta may have bugs.
4.0 beta:
