tho limit might change, as max count was 65k verts per Vector subGeom, and some mails from Adobe indicate some changes on higher side,
but havent looked at this in details with the released player as I'm using the prerelease drop players.
on the todo regarding this , MeshHelper, will hold a new method soon, that will take care of empty subgeometries,
Its also the case for FaceHelper
example: you load a 65005 vertices mesh, it becomes internally 2 subgeometries,
with the FaceHelper class, you can for instance say remove 5 faces in subgeometry[1]
this will work, but generate errors, because it will get a length of 0.
I dought seriously that you guys will get issues regarding this particular case in coming days.
I think it should be in there in a couple of days. Then you will be able to delete as much faces as you want
with no sorrows :)
