It's not the verts count that stops you.
It's the faces or triangle count.
Say you have any one face that numbers above 65535?
Such as 39/65536
You could crash S3D or it just won't import.
The reason is simple. The dat stores the face as 2 bytes. FF FF is the max you can store in 2 bytes. FF FF = 65535.
So you can have as many verts as you want as long as any one face does not number above 65535.

There's a reason S3D states Full Support yes or no for each Node and you'll notice full support for 3D Models is No.
I use 010 Editor to do what S3D can't.

65 000 ... so, the number I memorised first was about correct.
Just checked again the largest model I tried the last day -- I was wrong; it had not 100 000 but just 60 000 faces ...

Well, as said before, there are other good reasons for not using large meshs.

Thanks for the explanation.

That would explain why many textures are over lapped on UV's.
Once you understand how obj files do the faces? it becomes clear.
We can have a million verts coords as long as the actual faces do not go beyond the 65535 number.
(That is actually 65536 since hex starts with 0)
