import blendshape from maya

Hi Everyone. I'm a newbie unity user. I'm tring to import rigged model from maya that also uses blendshapes. I've watched some tuts that show that in the Inspector menu is possible to manage shapes with a slider. I can't see that slider. I've exported from maya an FBX file that has export blend shapes option ON. Next imported in Unity with import blendshapes ON in model inspector. Dragged in the Hierarchy menu. Now in the Inspector I can't see Skinned Mesh Render. Clicked on Add Component -> Mesh -> Skinned Mesh Renderer. No slider appears.

I can't find a solution.

Anyone could help me please?

Thank you in advance
