Legacy:T3D StaticMesh
From Unreal Wiki, The Unreal Engine Documentation Site
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.
