I am trying to learn how to composite in blender and render with Yafray. I cant seem to keep my background from being effected by the GI when boosting its value.
I am tying to put a simple orb in a parking lot. I don’t want the parking lot to change lightness (just the orb). I also want the background to still reflect light onto the orb and show its shadow.
Instead of adding the texture to a plane, make it the World texture and select the “Paper” option. You should get the same results without the background image being affected by the lighting.

Thanks for the tip. However this didn’t work with Yafray. Yafray distorts the image, as seen by the camera, and doesn’t fit it nicely into the render view. I will play around with the internal blender renderer to see if I can achieve the result I am looking for.
However, I would still like to use Yafray for compositing and any help using this renderer would be great.
Anyone have any blender files they would be willing to share to see how to set up a still composite?
These are the settings I have. They however also don’t work with Yafray.
I did actually solve my own problem though. If you uncheck ‘shadeless’ and set the specularity to 0, the picture isn’t effected (like shown in my first post). The traceable feature doesn’t effect this either (it can be checked or unchecked.).
Just set the GI value untill you get your desired results and then adjust the reflectivity of the planes untill the picture is back to its original exposure.
I am not sure if this is the only way to do this or why yafray behaves this way, but it seemed to work for me.
Thanks for the help from both mindblender and masterhoshi.
