View Full Version : Network rendering with FG

01-26-2007, 12:46 AM
I am wondering if it is possible to network render (using smedge doign packets not MR satellite) using a final gather cache file?

I can do this with Final Render, each machine adds to the cache file, this is with moving objects, so each machine adds per frame.

If I try this with mental ray each machine seems to wipe the file out and starts again per frame, possibly cencelling each other out

Any solutions??

Cheers, Nick

from manual(hope it helps):

The finalgather map copying and merging utility fg_copy is started as fg_copy [options] infile1 infileN outfile

It reads finalgather map files infile* created with finalgather file statements in the options block in the .mi scene file, and merges them into a single finalgather file outfile. Each file is a collection of finalgather points that represent the irradiance at a specific 3D coordinate.


This tool is helpful when rendering animations. Flickering is reduced with moderate computational effort if several key frames are rendered with final gathering saved to files. The -finalgather only command-line of mental ray option allows rendering these files quickly without rendering color images. When all the finalgather map files for the key frames are finished, the fg_copy tool can combine them into a single finalgather map file that can be used for beauty-rendering the entire animation. (This does not work for detail shadowmap (file:///C:/Program%20Files/Alias/mentalray3.5/docs/RefGuide/node80.html#INDEX264)s files.)
