X3d export from Blender


Can anyone with some experience working with X3D exports from Blender help me with an issue I’m having? I’m trying to export a model (of a building) with textures as an X3D file, so I can open it in Instant Player on Windows. Lighting seems to be missing from that file when I open it in Instant Player because I can’t see anything, really. It rotates and scales just fine, though!
