There are some things I do to fast rendering times (using only render to disk ! ). I try always to use the objects the most simple possible:an exemple, for modelling an house, I export from RDS5.5 a cube with boolean operations to let appear the doors and windows: after exporting, I use UV mapper program, make a template and a nice texture map in Photopaint. The simple object doesn't take much memory in Bryce and his rendering looks fine for a very short time. I only use complexes objects for the very near vision. I also use a complete hard disk drive for Bryce, nothing else on it and close all another programs during rendering. Forget not to close screensavers too. I hope that in the future Bryce.5 will optimize the rendering times. I thing
