My company developed with Spine 3.7 but for using UE4 UMG need to upgrade to 3.8 now.
There is some issues that needs tech support to make decision to upgrade 3.8
Backwards compatibility is not guaranteed when opening 3.7 work in 3.8 environment.
In case of Flip, when upgrade from 3.6 to 3.7 the mechanism changed but not guaranteed backwards compatibility.
and 3.8 changed Flip mechanism again but still not guaranteed backwards compatibility.
I have over 1,000 spine files with 3.7 so if there is no tech support I need to fix that one by one.When import a project, transform's value changed.
In 3.7 there is no problem when move child bone from project A to project B, in 3.8 transform's value changed.
Even if transform's value in parent bone is same but after moving transform's value in child bone changed.
Like as issue #1, Cannot load json file with version 3.7 on version 3.8
Because of these issues Cannot release engine update internally. and If can't resolve these issues, develop process will holding until resource porting done.
Please give me some tech support or guide to solve this situation.
