The link below is a 7zip package containing the blender scene, exported obj file, material and textures. When I load the obj in MeshLab it looks great although the normal bump map does not appear to work in meshlab, the diffuse texture is perfect. When I load the obj in the helix3d toolkit the results I get are less than perfect the UV mapping appears to be almost correct but then is completely wrong in other places.
I checked all the UV coords are in 0-1 range.
Also does normal/bump mapping work correctly in Helix3D viewport?
I solved this, actually its an issue with blender, for some odd reason creating a new scene in blender re-importing just the geometry and then re UV and set-up a new material with new textures then export and the mesh appears fine.
Not sure what was so wrong with it if meshlab could load it but its resolved.
