Key word here is 'likely' ... I have been running with
BIG_MESH for a couple of weeks and haven't hit a single fault.
I have done little more than just change the MFace struct,
with some cuteness so that you can switch back and
forth between big and small mesh with different
compile flags. Since we do have this cuteness, a nice
strategy might be to add the support for big mesh as a
compile option like it is in tuhopuu, setting it to default
when we are reasonably convinced any problems have been
Here is the patch:
Plus 2 files must be added to make the cuteness work:

Not verified. Well ... semi-verified in the sense that I
haven't had any faults in the last few weeks. I have had no
problems loading old blends, and I have had no problems loading
blends created with this version in old versions of blender.

#defines? I thought all numbers in blender were hard coded >=P
I just grep-ed for 65000 ...(which was hard coded in a few places.)

Not checked. I would appreciate if somebody who runs a lot
of scripts could test with the big mesh tuhopuu.

I am very unfamiliar with this code ... I would appreciate it if
somebody with a big mesh tuhopuu could test this.

Well, minus the overhead of storing the 200k faces in 4 different
