If you mean importing via transposer limits how you can position things. I think that is true, but I don't use it. I use native. Any GI option will add render time, of course there are times when it is really worth it. I don't think it is a bad or good thing, just differnt tools require a different approach. I did more of that a few months ago when I got c5 now I am spending more time using actual lights and all the options there. It is important to learn, it saves render time, gives more options and you can save the lighting to reuse. Irradiance maps are probably cool, but haven't even gotten to those yet :biggrin:.

No need to think outside the box....
