If your engine uses a different convention you'll have to modify them. G3D computes the normal map from the bump map on load, which is convenient because that's what the OBJ spec requires anyway and avoids convention issues.
I originally didn't include normal maps because they depend on the convention of the modeling tool, but it is easy to compute them from bump maps, which are unambigous.
Because several people requested normal maps, however, I updated the file with them and several other changes:
I added several of these to the G3D Innovation Engine's default music data. Thank you!
I added these to the G3D Innovation Engine http://g3d.sf.net.
The PNG exporter alpha-blended based on heightfield to white. I'll remaster the normals in the file.
