I'm getting an error in Unity when I re-export my Spine JSON into Unity. I've aded a new animation but I'm now getting this error and the new animation doesn't show up in my character Animation Controller in Unity. IS DOES however show up in my SkeletonData which is strange since I've re-exported this Spine file a number of times with no problems before, this is the first time I'm getting this error. My Animation Controller always auto-updated to match the animations in SkeletonData How do I get my Animation Controller to update to reflect the new animations added to SkeletonData? Is there a way to rebuild the dictionary or another way to fix this?

That makes total sense! Thanks for the quick reply. I'll check the Unity tutorial as well.

I'm having some trouble with modifying colliders during an animation and I was hoping someone might be able to shed some light on the proper way to approach this. My current development tools are Unity/Playmaker/Spine. I have a character that walks and jumps and does other moves that change his height. When the character jumps he tucks his knees which makes his height dramatically shorter than when he's in a standing position. This is an obvious issue since the collider doesn't scale to match the change in body height during the jump which presents immediate problems when jumping over things. What's the best way to modify the colliders during the jump animations. Should I be using a bounding box in Spine or is it something I should be modifying in Unity? I've attached a screenshot to better illustrate my problem.

I've tried it in a new Unity project with no other plugins and I'm still getting the same result. I'll send both the Unity and Spine projects to unity@esotericsoftware.com. Thank you.

I'm getting two recurring errors in the Unity console window that endlessly loop when I click on my character's SkeletonData file. As a result I cannot interact with any SkeletonData in the Inspector window. Anyone else running into this? Running Unity 5.3.0.

I just started a fresh Unity project and this is the first chraracter I've brought in. It's got 11 animations and 4 skins.

How do I go about changing the license name for Spine Pro?

The minimum number of computers is 5 though. I just want one educational copy for myself so that I can start to build a curriculum using Spine as part of the workflow. Is this available?

Hi,

I was wondering if you offered education discounts for university faculty?
Thank you.
