I have a fully functional 3D engine, but no way to create levels for it. Part of my engine is based on portal rendering, but in a vain attempt to be "different", I decided to build in support for concave cells/sectors. So what I need is either: a) a highly generic 3D modeling app that can be extended with the kind of custom data my engine needs (i.e. sectors and portals), and a plugin API to create the necessary exporter; or b) a way to subdivide any polygon soup into sectors so that each sector contains roughly the same number of polygons. If you have any suggestions, by all means let me know!

try MilkShape3D - http://www.swissquake.ch/chumbalum-soft/

I already tried MilkShape. It''s more of a character/weapon/whatever modeler, isn''t it? What I''m looking for is a level editor. It needs to be able to organize a map into sectors, and to mark certain polygons as ''portals''.

Essentially, what I''d like to find is a 3D modeler that allows me to attach custom, user-defined data to each and every primitive in the model.

You can download the source from they''re page, but I don''t know to what extend you''re allowed to modify. Just check it out...
