There are no special requirements for setting up the UVs for Static Meshes using the FBX pipeline. For Static Meshes, this is generally used to handle one set of UVs for the diffuse. The import of multiple UV sets is supported by the FBX pipeline in Unreal Engine 4. Automatic triangulation can lead to undesirable results. It will always be best to manually triangulate the mesh in the 3D application, controlling the direction and placement of edges. Triangulate the mesh in the 3D app - good solution, allows cleanup and modification before export.Īllow the FBX exporter to triangulate the mesh - okay solution, allows no cleanup but can work for simple meshes.Īllow the importer to triangulate the mesh - okay solution, allows no cleanup but can work for simple meshes. Model the mesh with only tris - best solution, provides the most control over the end result. There are several ways you can ensure your mesh is triangulated. Meshes in Unreal Engine must be triangulated as the graphics hardware only deals with triangles. Because of this, it is best to create your meshes at the origin, with the origin generally being located at one corner of the mesh to allow for proper alignment when snapping to the grid inside of Unreal Editor. The pivot point is always located at the origin (0,0,0) when exporting from a 3D modeling application. The pivot point of the mesh in Unreal Engine determines the point around which any transformations (translation, rotation, scale) will be performed. that you need to account for in order for the exporting and importing to go smoothly and for the mesh to work properly in Unreal Editor. There are some stipulations as far as setting up UVs, placement of the mesh, etc. In general, you are free to create Static Meshes using any tools and methods you want. Using a different version during export may result in incompatibilities. GLTF/.The UE4 FBX import pipeline uses FBX 2018. gltf file by clicking on File> Export for ARCode>.
