The above pic is Charysma with Vairesh's Total Hair. The file was built and saved in Poser 5. I rendered will max quality settings in Poser 4 (far left). Then used the P4 renderer inside P5 with max quality settings (middle). Then used Firefly's Production Quality setting. The time is in minutes and seconds. No changes were made to the file between renders. I used the default lights with one additional light. I disabled the shadow on the additional light. It appears Firefly may have rendered the 4th light's shadow anyway. I don't know, tho.
