I followed all instructions on stage creation wiki and imported all necessary assets etc (gStageEditor_1.9.0 package), but when i try to add collision layer to object, 21:Collision layer is missing from dropdown menu. Is there something wrong or maybe i have done something wrong?
this is a 'unity' issue, 'cause the layers are read at startup... I suggest to save the entire scene and project and retry, if not, try to close and reopen the project.
