Error in lightining during render

pedmpmar

I'm quite new to Daz and althought usually I can get a workaround most of the problems I encounter by doing some research, this one I can't seem to find answers anywhere.

I was trying out some new stuff I got from Daz Store a few days ago, being one of them the Render Sphere. I changed the background and removed all the lights that came with the product as I was only interested for now in trying the fog effect. When I decided to do the first test in Iray, I noticed I was both seeing the light from my back light and a black square from my key light. I found it odd because I was pretty sure I add turned off the render emitter on both, but went on to recheck it and in fact I did had switched it off. My second thought was that it could be something related with the Render Sphere so I went on to create a different scene without the render sphere but the same problem persisted.

Below I have a quick render of the first image and a screenshot of the scene setup where you can see what I'm talking about. My question now is, how do I solve this? Have I by mistake changed any setting that caused this?

Thanks in advance!

The Render Sphere was created for use in 3Delight, and doesn't work in Iray.

When Ilook at your setup, at the posistion that has the square, you have a light source. You will see the light source in the render (imagine a physical spotlight). move that out of the frame, and the square should be gone.
