Gotta love responsive customer service!!! :very_drunk:

And the limit in FS9 was 65K - until a few dev's figured out there was a loophole...

Here's some cool FYI info from a developer you probably won't get to know unless you ask...
Per the MSFS 2020 SDK, triangle (tris/poly) limits are based on LOD (Level of Detail) guidelines. These limits are designed to help developers optimize performance by reducing complexity at further distances. For example, a medium-sized aircraft should aim to keep its exterior model under 300,000 tris at the highest LOD.


However, with MSFS 2024, the approach is more modular. Individual components—like landing gear, cockpit, or even wear and tear decals—can now be split into separate LOD modules. That means you can have much higher poly counts per component, as long as the total LOD usage across all modules is managed wisely.


For instance, a landing gear module might now include 100K tris on its own, which would have been unthinkable in 2020. But since it's loaded only when needed and at close range, it's acceptable. This modular structure also allows for different LOD strategies per part of the aircraft. And will also explain why sometimes you have missing components in 2024 if the developer hasn't optimized the LOD's(Which is a pain in the butt btw) each LOD has to be made into a smaller POLY count until its a spec of a dot in the distance and the texture has to match it.

Some Dev's like myself only do one LOD level so you see the same thing close up as you do far away which is a big no-no, but most PC's can handle it, 2020 has proven that. This is also why Microsoft is eventually going to allow you to download an entire plane/scenery again and hold those files locally. ;-) ;-)


Typical module breakdowns might include:


  • Wings
  • Fuselage
  • Gear
  • Cockpit(s)
  • Decals (wear & tear, stencils, liveries)
  • Variants or attachments

So while the overall triangle budget may seem higher, it’s spread across multiple LOD-enabled components, each managed more flexibly than before. You might notice this when switching from interior to exterior view as it takes the model a split second to reload for you to see it. Also why in Multiplayer some things are outright missing in other players aircraft(Gear/Cockpit/Doors etc...)


Here is the old 2020 SDK recommendations:

I'm definitely picking this one up! I'm really interested to seeing how you programmed the flight model on this one. As a fellow dev (but not in the same league), I can't help looking at this stuff to increase my own knowledge. ;)

I, too, only create one LOD for aircraft (although mine are fairly simple models w/o many tris, relatively speaking). I am starting to look at creating one additional LOD (LOD001) just to provide a bit more efficiency.

Appreciate the work you've done and the amazing aircraft you've brought to the sim.
