problem with lighting styles - standard lighting

[alessandroM]

Good evening.

I have the following problem about inventor 2012: within the ray tracing of a set I am trying to insert the correct parameters, however I realized that in any way I go to change the settings on the standard lighting style (standard lights) absolutely nothing changes.

I can't get the desired lighting, so I ask for the help of you experts.

thanks in advance for vs collaboration
