Hi,

I'm having difficulty finding a general level/scene editor that can be used with a stand alone renderer/engine.
Editors are often part of a larger game framework (like Unity3D) and are only expected to be used in such an environment.

Unity also uses a proprietary binary file format (there's no XML-writer or similar), so I can't write an importer myself.

Any help?

Thanks

AFAIK the standard way to do this is to use a 3d modeling package such as Maya or Blender and export into a format which you can then import. You can have the ld's mark up a scene in a predefined way to indicate what type of game object something is.
