Open up Bryce on one of the machines and open Lightning on the other(s) To start the render, you go to File - Render Animation. Change the output module format to BMP sequence. Set (or Note) where you want the render saved. Click on the little dot next to Render on Network. Then click on Configure. Check the machine(s) running Lightning for the IP address (it's in the box near the top). Add those numbers to the the Client List (or Search) Make sure there is an arrow next to the addresses in the client list and click update. You should get a green dot if the computers are communicating. Make sure there is a check next to Use Host to Render (especially if you are only using two computers) and Tile Optimization. Click the check mark at the bottom and it should start rendering. It will render 100x100 squares on each computer and when done will stitch it all together.
