Hi there,

What is the average polygon count for good quality models in FS9? and what is the max FS9 can handle?

Cheers,

Jakes

As I know it:

Theoretically, there isn't a limit to what FS9 can handle. The usual is around 25k to 30k for decent aircraft, and 50k to 60k for detail. However, there are aircraft that use upwards of 70k or 80k.

I tend to keep my models below 40k, since that seems to be a sort of upper limit for older systems with FS.

Thank you, Coz the Cheetah D I am busy with is now about 25K without Landing gear and inside and VC

Sounds like you're right on track.

Polygon count (or is it vertice) is limited to 64K then the model will not compile.

This is per model so a VC will have it's own poly count seperate to the exterior.

I had to remake the Superfreighter twice to get it under the compile limit and I still have to be careful now and there are things I would have liked to have in it but can't. Cry

64k! THAT'S what it is! *snaps fingers and pops self in the head* Roll Eyes

But for FS9, the whole model must be under that limit, since it's one combined mesh. Only FSX can utilize the two model system.

The VC is a seperate model for FS9 until it's compiled and the two become one during compiling.

Before that both can be just under 64K

My Superfreighter is just under the limit and won't compile if even slightly larger.

Th partial VC which is the wing views etc, is a load more polys but it compiles OK because it is a seperate model at that stage.

At what point do you merge them? Before or after running MakeMDL out of Gmax?

I use FSDS via .X files

On MakeMDL the two models .x files are called in and then compiled which turns them into one.

I don't know how Gmax compiler works.

But the 64K limit applies to each model...not both (as a total)

In FSDS the exterior and the VC are seperate models each as it's own .fsc (Project).

Oh, I'm pretty sure you can do the same thing with Gmax, but I tend to leave them as a single file for the export process.

Understand: I don't work with them as one model, I merge them just before export.

In fsds you can call in another model on the current FSC and use the FSDS exporter but I use the .x file method.

I made a harbour crane in FSDS that busted the poly count too with only 27,000 vertices Shocked

.......and of course more than 67K on the poly count. Grin

Got a bit carried away with detail Cheesy

Goijg back to the original question

If it was a small light aircraft it could be very detailed with a lowish count but a big complex airliner, transport or bomber if highly detail is going to be a much higher count.

So there is no real answer as each job is so different in what is modelled and how it's done.

Actually, from what I understand, once you get past 65,000 poly's, the XtoMdl does kind of magic and another layer or something is created. I'm not sure how it works. This way you can theoretically use as many as you need. This is at 68k and I know I have gone higher on it. I think at one point it was upwards of 124k, before I corrected some things. Performance is another thing...

Is that FS.X??

TBH I can't see how there are than many polygons in that model...that is polygons before compiling

Afterwards there will be many more

It is FSX. It's been a lot more poly's in the past, plus you're not seeing the tops and bottoms of the wings. There's a lot of ribbing modeled there. Add to that the engine and cockpit and it adds up...

Wasn't it that the limit was 65k in FS9 and they removed it for FSX?
