When it comes to Ghost Lights, that's a product which purchase I don't regret a second. It has made creating lighting so much easier for Iray environments. I have also noticed that you lose skin specularity/gloss details, and skin looks kind of "bland" with just Ghost Lights, but I usually add IES emission profile from IG's Architectural lights set for my main mesh light. That seems to fix it without increasing render times.

 

Interesting. So are you saying that adding an IES profile changes the nature of the mesh light so that it brings out the specularity? If so, would any IES profile do that - for example from a site such as this?

I have to admit that I'm no expert in that area, so can't really answer that, but I assume so. I just know, that when I tried with pure Ghost Light setup, render speed was really good, but character's skin looked really bland.Then I added IG's architectural light in the scene, and I got much nicer skin. That unfortunately slowed render speed to crawl, so I replaced that IG's light with low-poly mesh light, and just added IG's IES profile to it, and then it worked nicely again 

 

EDIT:  I had to go back and take a quick test with this, and really couldn't see much difference on the skin depending on IES profile. The difference must have been that new light I added. Sorry about the confusion.

No problem - I will still probably try a few profiles anyway to see what effect they have on the light. I've found that render speed is very unpredictable for me anyway. Some surfaces and shaders are more likely to render quickly but also camera angles and light direction/intensity etc. So I'm far from an expert either and mostly rely on trial and error.
