I was able to get the RWR to export to work.
I added the following lines below, with "F14_F4E_RWR" being whatever you want to label the export in your MonitorSetup.lua. In this case, I use the same location for both the F-14 and F-4E RWRs on my second monitor.
--ViewportHandling
dofile(LockOn_Options.common_script_path.."ViewportHandling.lua")
update_screenspace_diplacement(1, true, 0)
try_find_assigned_viewport("F14_F4E_RWR")
Place at the bottom of the code in the following lua. Recommend using Notepad++.
DCS World OpenBeta > Mods > aircraft > F-4E > Cockpit > Scripts > RHAW > indicator > init_bake
I am continuing to work on the radar export but haven't had a lot of time.
