I'm looking to use Blender to create real-time low poly models for a OpenGL Performer program, does anyone know of a .blend loader for performer.
I really only need to load the textured model (but importing animation would be nice too!)
I'm sure I remember a post about this before but can't find any details of it...

the .blend file isn't well suited for loading from an external program
not that it isn't possible, or hasn't been done
but you may be better off with an exporter

python can export coordinates, vertex colors, and uv coordinates. (I don't know if you need more, python can do more... to an extent)

if you want the armature information there is no easy way.
loading the file is difficult
as is intperloating the armature defromation to determine the location/size/rotation of the bones (I don't know of anybody trying this yet; python has access to both the mesh before deformation, and after it)

you can export ipo curves for objects though

(I don't know anything about preformer, but you could probably write an exporter/loader yourself... and blender can export some things to vrml 1.0 and dxf)
