Painter baking error?

[rucybyron]

Hi, I am having a problem with the bake in substance painter on a simple model. This may be due to me being a bit of a noob, but I have not had this issue with similar models.

Here is the hi model - https://gyazo.com/be0afd27a9f1083d6865d3786c43b384

On the UV I scaled down the shell on the back and scaled up the front to get a nicer resolution as the back wont really be visible. When I bake the textures I am getting no detail on the front at all - https://gyazo.com/e2b5f93f6546d364ab6af3b13729f7a3

I am guessing this may be a simple error in my workflow but I am not sure what it is, any of you more experienced guys got a suggestion?

Much thanks
