Bulk edit materials?

[EddyNL]

Hi all,

Unreal noob here.

I’m working on a large scale city scene in Blender and would like to bring that into Unreal.
For all materials I’d like to have following settings:

Specular 0
Roughness 1

Whatever settings I try in Blender or Unreal, everytime I import into Unreal it ends up having nothing connected to the Specular port.
I really don’t want to go update 100+ materials every time I import my model.

Is there a way to bulk update materials in Unreal?

(I know there is this Property Matrix bulk edit for textures, but for materials that options seems to be missing)

My workflow:
Blender → export .glb or .gltf → Unreal: Import Into Level

Hello, maybe this can help you GitHub - 0xafbf/blender-datasmith-export: Blender addon to export UE4 Datasmith format

Hey, thanks for this!
For simple materials it works fine, more complex materials need a bit more work.
