In conclusion with the current Bryce to get realistic play of light will take a lot of lights and an enourmous amount of render time. I would love to see besides the faster render time that AS says DAZ has planned. The ability of Bryce to do actual radiosity and actually bounce light several times off of objects. I would also like to see a material setting to set the amount of light that material reflects back into the environment. Black surfaces would reflect very little to no energy back into the environment while white ones would reflect maybe 95% back (some is always absorbed by the material).
