If you cannot find them in your current project (PhotoRendering Settings > Scene:
Select and Mange Scenes...), open a Template file (Applications > Graphisoft > ArchiCAD 19 > Defaults > ArchiCAD >
ArchiCAD 19.tpl file), open its
Select and Mange Scenes... and export the scenes from there for import into your current project.
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
