So I have tried to export my Left/Right DDI's for the hornet onto a 4th monitor. I have the monitors in a triplehead config then the 4th below the center to make a "T" shape. My cougar MFD's are attached to the monitor, and I have set up the DDI output to be in the appropriate positions. I do get the data output as expected, but what I didn't expect is for the cockpit camera to also be rendered behind the DDI data instead of a solid black background. Below is a screenshot example of what is happening. I started with one of the canned .lua files (Camera and Right MFCD I think) and built onto to it to add the positioning and GUI position and aspect.
I'd appreciate anyone's input as to what might be going on. The canned monitor setup files work, but when I modify them and use my version with both the A-10 and the Hornet, I get the full camera render in the viewport. Strange.
