Your issues have nothing to do with LOD
Black textures usually means missing textures,so a corrupted install IMHO
Or it could be a corrupted config.ini but I highly doubt that and would lean towards missing textures
If it was an LOD issue,then you would not see the object at all,
at which ever Level Of Detail of that object where it was missing
So the object would NOT be visible from a distance...
and then BANG POP-UP in your face instantly once your very... very... close
The T.o.W. objects are objects with LOD issues
and they are the only objects with LOD issues
Do to not being imported from ToW properly
I have seen objects ,planes,even complete maps etc. etc.
with black textures
Every single time it was missing textures,
or in case of a whole map being black then it was a corrupted config.ini
Sorry,but your install has issues and has nothing to do with anything else
My testing game,is a DVD Patch thrpough accordingly to 4.101m
Then I have downloaded the Public torrent,addd all RC patches HaDeS has made available...
and I have added nothing to this install or tweaked anything including nothing done to my config.ini
And I do not have these black textures,nor numerous other things that have been reported
Usually it all comes down to a corrupted game or install
Starting over and re-installing everything is all I can suggest
It takes me less than an hour to do a complete new install
An hours worth of time and energy and your problems could be solved
In most cases a re-install usually cures things like this
but of coarse that is only IMHO

I'm using perfect detail.
I think is something about LOD.
