FBX LOD UE4 export is it possible at all?

[staughost]

Is it possible to export LOD tree (multiple lods in single file) to UE4 without having the need of exporting each individual LOD level?

1. create an empty with the name “LOD_ObjectName”
2. create a custom property on the empty: name = fbx_type, value = LodGroup
3. parent each object (LODs and original object too) to the empty
   – order of parenting matters, not prefix in the name
   – original object should be parented last
   – e.g. LOD1, LOD2, LOD3, LOD0 (original object)
4. select the empty and all the objects
5. export
6. this works for static meshes, though last time I tried with a skeletal mesh, the order in UE4 was not always correct

Pain in the ass, so just use this addon to automate it or write a python script.

GYAZ Export Tools (Seamless Blender To Unreal/Unity (FBX))

Last Update: March 1, 2023 for Blender 3.4 Seamless Blender To Unreal/Unity Export The addon focuses on moving assets from Blender to Unreal/Unity making iteration painless using Blender’s default FBX exporter. Blender vs UE4 standards: Blender: -Y is forward, +Z is up, 1 unit is 1 meter UE4: +X is forward, +Z is up, 1 unit is 1 centimeter The addon expects assets to be correctly set up for Blender. Do not divert from Blender standards because the addon won’t work then, and it also breaks …

the addon discovers LODs by object name prefix

• ObjectName
• LOD1_ObjectName
• LOD2_ObjectName
