Imported meshes and lighting

Hi everyone,
i’ve imported a mesh from blender into my scene, but i’m facing different behaviour with spotLights.
Comparing to BABYLON standard material the imported meshes are very dark. What could be the cause: am i supposed to set different material in blender or some settings in Babylon?
This is my PG:
As you can see the sphere is shining while the forklift is totally dark.

If i use an emisphericLight all seems to work as espected.
Thanks in advance

This is because you are using PBR materials without having an environment texture defined in your scene:
