Legacy:T3D StaticMesh

T3D Staticmeshes files are generated with the UCC command in order to export all StaticMeshes data from package or level. It created one .t3d file for each unique staticmesh found in the package. They are exported using this command: ucc batchexport myPackage T3D StaticMesh

Sample File: (some basic triangle) Triangle in Unreal Editor:

Begin StaticMesh Name=TriOriginal
    Version=2.000000 BoundingBox.Min.X=-128.000000 BoundingBox.Min.Y=-128.000000 BoundingBox.Min.Z=0.000000 BoundingBox.Max.X=128.000000 BoundingBox.Max.Y=128.000000 BoundingBox.Max.Z=0.000000
    Begin Triangle
        Texture SMTest.Tex.256x256 //Texture applied to the triangle
        SmoothingMask 0 //Unknown effect
        Vertex 0 128.000000 128.000000 0.000000 1.000000 0.000000 //Vertex Coordinates (x,y,z)+ Texture U,V data
        Vertex 1 -128.000000 -128.000000 0.000000 0.000000 -1.000000
        Vertex 2 -128.000000 128.000000 0.000000 0.000000 0.000000
    End Triangle
End StaticMesh

The vertices are ordered differently from the last one to the first one if we compare with T3D brush.
