Excusue me for late reply. Unfortunately, you can currently use versions 3.8–4.0. However, if you select 4.0 when exporting JSON in Spine, you will not encounter any issues.
Hi LizardWish,
No problem at all, I just wanted to know what the latest supported version was before trying to use it on exported models.
I appreciate the reply, and I will purchase this when I get home tonight.
Thank you
