What are some things to consider when, in bryce, doing lighting? tips? shortcuts?

Really lighting all depends on the scene. Is it outdoor, indoor, has torches or candles? Each situation requires different set-ups.

A good thing to do is to observe set ups in films or TV or in your environment. It can be a case of trial and error at first, but experiment just with an object say a sphere and try the different lights changing the settings in the lab. Also different atmospheres affect what you do as well. Light gels are also worth messing with from tim to time. There are a couple of tutorials out there. The best source I've found is www.3dlinks.com, this site covers a number of techniques and there are a couple of good light tuts.

Things to watch out with in bryce are soft-shadowed lights. Be sure to only set them to softshadow if you really see the effect otherwise it isn't worth the skyrocketing rendertimes. Thethreelight setup is one of the most often used lightingsetup. The setup is made with key-lights, backlights and fill-lights. Key-lights are the main lights in the scene. The fill-lights are usually dim and are used to add some depth to flat and lifeless shadow area's. Backlights light objects from behind (obviously) and are used to make objects stand out more.
