FBX scene import data issue.

Hi all,
Having an issue for sometime with ue4.

If I add a new mesh in my scene in the 3d package, on re-importing using the fbx scene data import, the newly added mesh being imported into ue4 displays this triangle icon. It imports fine, but if I close ue4 and the next time I open the engine, this particular mesh is not in the scene or content folder.
Any ideas how I can fix this or is the blueprint corrupt?

Did you save the files in the content browser after reimporting the scene?

I normally save using the save all option so it saves everything to disk. I think I figured out the solution. I checked the fbxscene blueprint, seems the name of the static mesh is there but it is missing. I deleted the name from the blueprint. So I reimported the fbx scene again with the triangle icon, the missing static mesh is imported. I then reimport the fbx scene one more time and right click the problematic mesh in the import options, and click replace existing mesh with the new imported mesh in the content folder and save all. Seems to work now, every time ue4 is closed and reopened. Don’t know why but it works.

Maybe the save all doesn’t work with the content browser or there is a problem with the fbxscene blueprint referencing added new static mesh to the scene.
