I find it is easier and quicker to use mor elights in tightly grouped arrays than it is to use soft shadows.  I use light domes and light groups to get soft shadows.Soft shadows in Bryce are amazingly slow. I fidn that 3 soft shadow lights are slower than 100 hard shadow no falloff lights. Remember too no falloff. >     Sort of as an experement I rendered a pic with 60 lights and another with 3 soft lights the 60 is substantially faster. People don't play with light domes because they are slower but because they simulate soft shadows and true ambeince faster than setting up a render for those things. My 3 sot light s is still at it at least twice as long as the 57 light rig. I have preset ligting rigs for this I made my own after I took a few of the ones available and disected them.

Okay... I've turned the soft shadows off on all the 3 lights, and instead of something like 7 days 21 hours etc etc it took 1 hour 31 minutes... I'm not sure if it's an improvement or not.

In a situation like this (i.e. inside the building) I have no idea how to place a light dome or where to put more than the 3 lights I already have, and won't more lights bleach out the scene?

Here's the image now, what do you think?
