In the tab "StandAlone" when you press "Upload", the uploaded standalone scenes are duplicated in the folder "../YourLightshow/StandAlone/scenes/" under the names "button1.sce, button2.sce, button3.sce, ...".
You can open these scenes in "Editor > Steps" to check them.

Note: the possible existing files called "universeX_buttonY.sce" are ignored by the current software version (they were generated by an old version of the software under another format which is not used anymore).
