The FBX_Import_Options map shows some of the options that can be set when importing an FBX asset into Unreal Engine 4.
When importing a Static Mesh, Skeletal Mesh, or Animation asset in FBX format, you will be presented with the Import Options dialogue box as seen below.
Depending on the type of asset being imported, additional options will become available such as importing an asset along with its materials/textures, LOD
options as well as animation and morph target options.
You can find additional resources for each example by clicking on the example's name.
