Disable Reflections and Gradients in Shaded Drawing Views

Issue:
When you create a drawing view of a part it shows a gradient reflection that is not present in the model. This can cause confusion concerning paint color specification and sometimes feature representation, depending on the geometry involved.

Solution:
Autodesk has provided a method for disabling these reflections in the form of a registry edit. To change this behavior you can add a DWORD registry key named "Suppress Specular Color" with any  value greater than zero.

(Note: if you looking for how to turn off the reflective image used for shiny parts in the model you can find that tip here: http://inventortrenches.blogspot.com/2011/03/change-reflection-for-shiny-parts.html)

For Inventor 2010:
