Why is my imported Maya model becoming distorted?

When I import a model from maya it becomes weird.Here is the picture:

Also an error when imported about degenerated tangent basis.
Help please

Hey SongOfDeath -

Some quick questions about your model to help us narrow down the problem. Is this a skeletal mesh or a static mesh, I am assuming its skeletal but it doesn’t hurt to check. Can you give us a screenshot of your import and export settings from Maya and UE4? Again more of a check, but what versions of UE4 and Maya are you using (4.1.1? and 2014?)

Thanks -

Solved by using FBX 2013 version instead of FBX 2014
But now i have another issue, it doesn’t load the normal maps and low poly model shows up.
screenshot from maya :

The model in maya I put a screenshot on is a 7k poly with normal map on

Ok, awesome. what were your import settings when you brought it into the engine because it looks more like your smoothing groups didn’t export properly from Maya.

Here are the geometry exporting settings and fbx version settings :

fbx 2013 :

Is it because im using maya 2015, someone please help normal maps aren’t working when imported to ue4

Try unchecking “Smooth mesh” unless you really need that extra tessellation. Second, what are your import settings. Are you importing normals or letting Unreal calculate them?

Hey SongOfDeath -

Maya 2015 shouldn’t be the issue as long as you are using the FBX 2013 export options. Your Maya export settings look ok, I would have to agree Matt it has to be in the import settings and how you are importing the mesh. Take a look here for normal importation.

https://docs.unrealengine.com/latest/INT/Engine/Content/FBX/ImportOptions/index.html#basic

Here are my import settings, tried with:
import normals,
import tangents and normals,
and calculate normals still the same results.

When I Uncheck smooth mesh maya imports but gives a warning :

When i try to import the one without smooth mesh option unreal engine crashes.

I think the engine isn’t importing the material because my normal map is attached to the blinn material in maya and i can’t see normal map attached,also can’t see the shiny blinn material in unreal engine
