First your Assembly File will not show because the parts are not included. You need to do a Pack & Go so all the parts are sent with the assembly
Reflections are influenced by, Environment, Rotation of Environment, Scenes, Materials and Lights
When you first start to Render you need to experiment! Delve into all the setting. Practice, practice, practice!
Standard No change
Rotation of Environment
Thanks for your reply.
I have already tried all those, and even tried to change the solidworks light settings, but I think I messed up the settings, and now, it only renders only half of my module. Also, when I try changing the scene and environment, all differences I got was the darkness, and couldn't get the reflection on the back panel of the phone. I have attached the Zip file of my assembly and I will attach some of my rendered results.
