Speed up render time.....

I had one particular file quite some time ago. A fairly simple scene except the was this hair trans-map on a poser that would make my white line come to a screetching drag!! So, I turn off the appearance of the hair in the attributes of that part of the model, let the entire scene render. Afterward I could plop render small segments of the hair. This works great when you're planning on going somewhere, open the file, let-her rip, come home, Voila!! Save it and do thia all over again until the difficult area is complete.

Another thing to remember too, when you're building a scene...and let's say the front of the building isn't visible in your scene, don't build the entire building.......Only what is going to show.

After time you can also determine when an effect like distance blur and motion blur are easier done with a distance map and Postwork--VS--a long render with DOF set up in Bryce. This saves tons of time.
