Hi I have noticed that lighting can be difficult to get just right in C4. You have to be able to picture what each lighting element you use will do. The problems start when (as frequently happens), the lights do not do exactly what you think they will. I do a lot of starship models in space. I ende up using limited range bulb lights with light spheres for glow effects on the ships engines and weapons. I also use distance lights to create the low level ambient lighting I need as well as sunlight from stars. It can get tricky doing this without overlighting the scene. I also play with the shadow properties of different objects and lights. I typically do about 50-60 test renders at low resolution before I do the final high resolution render. I persomanny thing they could have made some of the lights easier to use, I have yet to figure out shape lights or tube lights. Im hoping to play with them soon so I can use them for weapon shots. Just remember Never Give Up, Never Surrender...
