what types of lighting setups do you use to evaluate changes you make to your character with morphs?

I didnt know if there are specific render settings I should be using or presets that i should switch between for iray or what kind of different lighting setups and hdris I should use to see how my changes effect its relationship with light. I noticed a big change in  how things appear in studio 6 when in iray and i dont know if I should use 6 over 4 or not.

Do you mean in a final render or in the viewport? In the final render, they output should look the same whether DS4 or DS6.

In the viewport, there's nothing that will show you the lighting accurately except Nvidia Iray Draw Style.
