FFbxImporter

Flag that the mesh is the first mesh to import in current FBX scene FBX scene may contain multiple meshes, importer can import them at one time.

Value is true if the file was create by blender.

Base path of fbx file

Set when importing skeletal meshes if the merge bones step fails.

We cache the hash of the file when we open the file. This is to avoid calculating the hash many time when importing many asset in one fbx file.

Compute the matrix for skeletal Fbx Node If we import don't import a scene it will call ComputeTotalMatrix with Node as the parameter.

Compute the global matrix for Fbx Node If we import scene it will return identity plus the pivot if we turn the bake pivot option

As movement tracks in Unreal cannot have differing interpolation modes for position & rotation, we consolidate the two modes here.

Convert the scene from the current options.

Meshes

Find the all the node containing a mesh attribute for the specified LOD index.

Create materials from Fbx node.

Add a basic white diffuse color if no expression is linked to diffuse input.

Fill the Points in FSkeletalMeshIMportData from Fbx Nodes and FbxShape Array if it exists.

When we get exported time we call GetanimationInterval from fbx sdk and it return the layer 0 by default This function return the sum of all layer instead of just the layer 0.

Get Animation Time Span - duration of the animation

Calculate the global Sample Rate for all the nodes in the FbxAnimStack pass in parameter

Get the object of import options

Detect if the FBX file has skeletal mesh model.

Returns the importer singleton. It will be created on the first request.

Make material Unreal asset name from the Fbx material

Calculate Max Sample Rate - separate out of the original ImportAnimations

Return the node that match the mesh name. Return nullptr in case there is no match

Get Unreal skeleton root from the FBX skeleton node. Mesh and dummy can be used as skeleton.

Get detail infomation in the Fbx scene

Get Unreal Interpolation mode from FBX interpolation mode

For matinee export Retrieves whether there are any unknown camera instances within the FBX document.

Help
