Hi!
I purchased the superb GTN 750 addon a few days ago and since then I've been trying to get it in the default Cessna 172 from Laminar Research for XP 11.10b5.
I also have the Reality Expansion Pack for the C172, but it's not compatible with the latest v11.10 yet.
As you may know, there was a compatibility mod for the C172 including two GTN 750 in the cockpit.
I managed to adapt it to XP 11.10b5 and decided it should be interesting to update the GTN 3D model and textures.
I heavily tweaked a base model (from a payware) and created my own textures and effects.
The result you can see on the pictures below is a new model with accurate dimensions for the GTN, with custom textures and UV map (1024x1024) including night lighting, a PBR screen surface with reflections and subtle "dirt", but I had to ditch the master selection button from the original mod as I'm not familiar with the animation and logics process for the interactive elements. The original buttons remain functional (knobs, DTO, home).
I just wish it would have been easier, as editing the cockpit interactive elements can be very tricky. Unfortunately, I can't afford the time to get into that level of details - so I kept the original layout with two GTN units.
The current result with the default 172 is fantastic, and I'm really grateful we have the opportunity to use such an in-depth GTN device in X-Plane.
Thanks to Reality XP and Jean-Luc!
Mille mercis pour cette superbe réalisation !
