I have a unity project with tons of spine animations all done in 3.x.
No I have an animation done in 4.0 and There is no way around it how I can import it.
When I import it in unity, It doesn't work asking to upgrade to 4.0 runtime which I can't do because all the other animations will be ruined.
What should I do?
Also, worth mentioning that when I tried to use spine editor to open the files "JSON" it gave me all missing on all images so I couldn't work that out too.
Issue with spine animations 4.0.x and unity
Unfortunately, it is not possible to integrate multiple versions of the spine-unity runtime within a single Unity project, so the only way is to match all of your Spine projects to 3.8 or 4.0.
Regarding the issue of images being missing when importing JSON files, if the images path is corrected to an appropriate one after import, the images will be displayed properly. Did you try it because you want to downgrade a Spine project created in 4.0 to 3.8? If you would like to know the detailed procedure, please tell me what you want to achieve by importing JSON files so that I can explain it.
Misaki You are correct, I only have the json, atlas and png and want to downgrade it from 4.0 to 3.8
So I found out "from kind people on discord" that I need to use texture unpacker, I did that and managed to load all images but now a bigger issues appeared.
Multiple regions appear as "pro only", I don't have pro version only ess and all I want to do is just re-export to downgraded version.
Fall1n1 Thank you for elaborating your issue. I am afraid that skeleton files created using any feature for Spine PRO can only be opened using Spine PRO, because there are some features that are not available in Spine ESS, for example, it is impossible to display a skeleton that uses meshes in Spine ESS. If the skeleton uses only a few meshes, you may be able to ask someone to create a converted version that does not use PRO's features, but it would be nearly impossible for animations that can only be expressed using meshes.
