For the L-1011, I’d first check the aircraft’s SDK or variable documentation rather than assuming those values use the standard MSFS names. Vertical speed and selected altitude may be exposed as standard SimVars, but EPR is likely aircraft-specific and could be an L-1011 custom variable. In AAO, the variable/event inspector can help identify what the aircraft actually exposes, especially if the developer has implemented custom L-vars or H-vars. For the INS panel, separate transparent PNGs for the panel background, knobs and buttons would be the easiest way to animate individual elements in GlassOut. If you only have one flattened image, you’d need to edit it into separate layers yourself. I’d also test one knob and one button first before building the entire panel; that should reveal whether Hanger Control and GlassOut handle the animation and input events the way you expect.
