Repeated six times... tell you what, can you please send
me your .ct file to take a look at, a screen shot would
be great too.
Are you perchance using a .flt model with your cliptexture?
If you are also using clip- or perfly to view it, you
have to use "-y flt,20,1" on the command line to activate
the texgen needed for correct clipcentre placement.
There is a corresponding pfdConverterMode() call which will
do the same in code.
Symptoms of this particular problem are squares of decreasing
size but increasing resolution, like a mipmap displaying
every level of detail.
Cheers,
tzelin
