Description

The fbx exporter should support material instance to export the same result has the user see in the content browser or in the level editor.

Steps to Reproduce
  1. Import a staticmesh
  2. Create a base material with a vector parameter hook to the "Base Color" input
  3. Create a material instance from the just created base material
  4. Change the vector parameter color in the instance material
  5. Open the static mesh editor
  6. assign the material instance to the first material slot
  7. Export the static mesh to an fbx file. You can use either level export or asset action export.

RESULT: The fbx file will use the base material color instead of the material instance override color

EXPECTED: The fbx file use the material instance color

 

-A second thing that do not work

drop the staticmesh in a level

change the UStaticmeshComponent Material override to use a different material with a different color

select the staticmesh actor

Click menu File->Export Selected

Export to a fbx file

RESULT: The fbx file do not use the component overriden material color

EXPECTED: The fbx file should use the component overriden material color- This is now being tracked in UE-960083
