I currently have a scene rendering on my graphics only PC.  After 14 hours it is 7 percent complete.  This is going to be multiple days long, maybe a week or so. Since the PC is used only for graphics and I have a second PC for web stuff this is no problem.  I two questions:

If Bryce is rendering to a file, what would happen if you try to access that file in another window?  Will it crash the render or can you see the progress?

What is the longest render you have ever successfully completed?

 

oops that was three questions.
