Everything work well one day and everything stop to work the other day ! I did more animations and i reimported in my project ! But animation cant be reimported anymore from the new .gbl file and i dont know why i did take the same setting for exportation . I did replace the .gbl file and overwrited it but i cant do anything beside replacing the AnimationPlayer by hand but i get a Imported Scene Advertissement and i cant load more animation unless i overwrite the AnimationPlayer ! =/. So should i redo everything or just play around with every files ! X_X. Also what is the best way to have multiple cloth and Tools . Thanks !
