All versions of spine 4 and probably earlier
After careful testing, I noticed the following:
If during export you open the folder where you saved the project (usually), create a folder there and select it, then the selection does not occur. Unable to select a folder in the Windows file|folder selection window. If you write a name in the file field, any, then the save button works. But this is inconvenient, because in the Output-prefix line in the file export window, you have to delete the garbage.
- Click by [Output-prefix] select path
- Create [Output] folder
- Select C:\Spine\MyProject\Output <- Don't work
Output-prefix: C:\Spine\MyProject\Output It is not possible to choose.
You have to write abracadabra in the file selection window. After that, you can select the export folder, but the path is the following
And then delete: abracadabra
in order to keep the sequence of png to Output
Version of my spine is 4.1.15
