My Light is not shining on the lit side of my imported object For some reason my imported object is absorbing all the light, it does have some reflected light but none on the side it is lit from. I've tried increasing the light source but it doesn't help.

As you can see the object is sat on a plane and the plane is acting correctly to the light.
Some imported objects have normal problems and display black artefacts, so in  Properties panel > Object Data > Geometry > click on Clear Custom Split Normals Data.
