I have a set of blend shapes (made in Mudbox) for this character that I´m working on. But when I import the fbx file (or obj file) to Maya and aply them to my original mesh and hit the smooth preview (with the "3" key), the blend shapes loses a lot of detail.

I´ve already cheched the inputs in my main mesh and they are in this order (Skin Cluster, Blendshape, Tweak). Even the imported mesh with the blend shape loses detail when I hit 3.

Is there any way to achieve the same detail from Mudbox to Maya using only low poly meshes??
