Thank you for your reply
I mean the Animation Event parameter.
witch you can set int, float string, audio path data to use on frame time.
when i set all of 3 parameter to key frame event on spine editor.
and export it.
it works. i can find all the data i have set on spine json file.
but when i import it to Unity Editor.
and check frame event on animation clip.
int, float parameter data i have set is gone.
only string data remains.
and if i set only int, float data on spine.
then only float data remains.
do you have any clue how to solve this problem?
