UV maps and subdivided mesh issues

I've made a low poly model, created the UV map and loaded it up straight into Unity (OBJ), and it works absolutely great (Yay my first model in Unity).

But I'm having issues when I try the same thing with the same model, but subdivided for better quality.

The OBJ imports just fine, and shows up all smooth just as it should, but no matter what I do the UV map just doesn't have any effect.

I made new seams and a new uv map, colored it up, but no go, in unity the high poly version is just all grey (The low-poly eyes accept the uv map and works, so the issue is with high-poly)

Am I missing a step somewhere? A setting?

Some ideas:
Did you check the import setting in Unity (import materials, etc)?
Try applying any material with a texture map you already have in your scene to check if the model has UVs at all. If the texture map is on the model, its ok... If it appears in a single color or obviously screwed up, then the OBJ didn't come out of Silo correctly, this happens. Try opening the model in another program (i use Unwrap3D, but any free modeler out there might work, like blender) to see if its the same.

If the UVs are lost, go back to your *.SIB file and reexport. If the OBJ is the only file you have, recreate the uvs (i know, it sucks).

If nothing works, write again or attach the model, i'll check it out.
