1-Download the WB and Max project files from the free stuff or from the WorldBuilder database.
2-Load both GreenhouseStart.awb and WBMaxStart.max.
3-Goto WorldBuilder and add a "Max Communication Object" by clicking the icon on the left toolbar.
4-Goto Max and click "Rendering > Environment"
5-Click "Add" under Atmosphere to add the AWB Max communicator in Max.
6-Under AWB Communicator click "Connected" to connect both packages and click "Fit units" and "Fit frames" so frames and units are the same in both packages.
IMPORTANT!!! Build your Max models in meters or convert the Max model to meters so the scale will
match in the WorldBuilder scene.
