using 737-800 SP1, both had same issue with original version. After install NGX ,FSx only sees 737-800 no wingletAfter few days investigating found i could fix the problem by passing the alias of other variant panels to 737-800 no winglet , and copy the entire 737-800 no winglet folder to the other variants.In short looks like the alias is failing for the plane, cause soon as i copy over all the panel files including panel.cfg from the main copy in 800 no winglet all is fine, fsx sees all variants.I am not comfortable with this soltion cause1. i have to maintain 4 copies of NGX panel.cfg2. NGX performance config goes crazy due to this chnage so cant chnage it from its defualt high res settings.3. plus who knows what elseI have most all other pmdg stuff , plus other addon that use panel aliasing but none has this problem.IKO Woods
