I am at a loss for what causes (the attached) incomplete photo rendering made up of partial image bands, and am open to any suggestions. The PLN file is approximately 11 MB with the buildings as multi-story modules (5 stories total). The roof utilizes the Italian tile roof surfacer, however that layer is off for these renderings. The Open GL engine works as expected, but Lightworks does not fully render the image (even with low level settings). Light Sources is set to lamps (sun and sky objects that are turned on in the plan window), with shadow casting by lamp settings. Other smaller PLN project files photo render as expected.
