Model only appearing in one eye

Hi,
I have an imported 3d model. Worked fine in Oculus in one of my projects. I then migrated it to another project and now it only renders in one eye.
I have tried it with a different textures etc all with no luck. Tried playing around with the normals/lightmap tickboxes and so on, still no luck.

Other maps in the same project load all objects with no problems. Anyone got any ideas?

Thanks

Try to reexport the model and import it again. Is it something special or just a simple static mesh?

Are you using 4.7?

Yes using the latest preview build of 4.7. Tried re-exporting and re-importing with the same result. It is a simple static mesh. If I open the same model in a different project.
Also I should say the model looks fine in 2D mode but as soon as I Alt-Enter to stereo it goes bad
