Actually, Unity did need .json.txt
back in Unity 4.1 or 4.2 or something. It might have even been 3.x. Too long ago.
I think enough people complained that they now recognize .json
.
But I second this. Please allow Spine editor import data (and SkeletonViewer) file pickers to recognize .bytes
.
What's cool/sad is that SkeletonViewer and Spine editor already recognize .atlas.txt
. :p
