Is there anything other then that black ball to even reflect in the scene?

Also is that a poser ready item or something you imported? Try it first on a simple poser ball prop, learn what's going wrong with that, and then try that on a complex item.

Only guess I can make is checkmark "normals foreward" on tjhe car's body material.

Looking at the top of the driver side door, it does appear that normals are NOT all facing forewards in that material. See the reflection at the top of it that appears to be floating above he door?

Also update your poser to the latest release, not just the first poser update.

Way too many people take way too many things way too seriously.
