Shonner: I know your pretty good with Carrara, however let me highlight the problem, which is with me and not the software: This project is to be an experiment with all sorts of lighting in one scene, heres a new render where I have progressed a little. (notice the building in the background where my experiment of lighting the windows has begun, quite pleased with that!) I have used a different model of a car and placed it half in the light and half out of the light and this is giving me the desired effect, the car is lit correctly. My problem is in the final scene I will use different cars (dont want clones!), which will have to be carrara native cars as I do not posses others, but in the first image it looks the same in or out of the light. Now I know its not a lighting problem but a shading issue that I still cant figure...
