Problem with FBX import

Hi everyone, sorry my bad english…I have a problem when i import a fbx mesh:

I use Blender…Where is the problem?

Then i have another issue, if i create a cube in blender, and i apply a material as: M_Ground_Moss for example, the result is this:

Why? Thanks!

Pic 1: It seems your normal of the top plane is reversed. You can ensure your normals are facing the correct direction in Blender for exporting. For a quick check, you can try checking “Two Sided” inside of your material properties which will ignore culling the backfaces. I would fix the reversed normal though as it would be the correct fix.

Pic 2: It seems yo have no UV mapped to the cube.

Good luck!

Thanks! I have resolved my second problem! But with the first…i don’t understand…Where is “Two Sided”?

Looking at the shading, I don’t think there is a top plane. @Baziga, is the top model meant to be a hollow tube? If so, look up “Back-face culling”. If it’s hollow, you do need to see both sides so open up the Material you’re using, and turn on the “Material → Two Sided” checkbox in the Details window.

Yes! The top is hollow! Maybe I 'm wrong something… Because i don’t understand well the english ahaha it’s right? Because doesn’t work :

Oooooooh!!! With two sided in Material of UE4 i have resolved!!! Thank you Devero, etheranger and Luos!! You are the best guys!!!

open the material you apply to the cylinder. (inside ue4)
bottom left in the menu there is an option called two sided, enable that.
