  ok, I think you forgot to set all to cross... Persides, I did actually ask for left, cross right red, on every room...

=========
C0 0 x B 8 0 1 F 8 001 2CF
0 OK 1x4 0.5 NoMirror NoClamp
1 OK 0.1x4 0.5 NoMirror NoClamp
2 OK 0.1x4 0.5 NoMirror NoClamp

B Corrupt 8x1 0.5 NoMirror NoClamp

C Corrupt 1x1 0.5 NoMirror NoClamp
D Corrupt 0.1x1 0.5 NoMirror NoClamp
E Corrupt 0.1x1 0.5 NoMirror NoClamp
F Corrupt 8x1 0.5 NoMirror NoClamp

So Correct Values are 3,7,B & F
This indicates bitflags 8421 where 2 & 1 bust be True.

==================

C0 0 B x 8 0 1 F 8 001 2CF
0 OK 64x0.5 0.5 NoMirror NoClamp
1 OK 64x0.1 0.5 NoMirror NoClamp
2 OK 64x0.1 0.5 NoMirror NoClamp
3 OK 64x4 0.5 NoMirror NoClamp

4 OK 32x0.5 0.5 NoMirror NoClamp
5 OK 32x0.1 0.5 NoMirror NoClamp
6 OK 32x0.1 0.5 NoMirror NoClamp
7 OK 32x4 0.5 NoMirror NoClamp

8 OK 16x0.5 0.5 NoMirror NoClamp
9 Corrupt 8x0.1 0.5 NoMirror NoClamp
A Corrupt 8x0.1 0.5 NoMirror NoClamp
B Corrupt 8x4 0.5 NoMirror NoClamp

C Corrupt 4x0.5 0.5 NoMirror NoClamp
D Corrupt 4x0.1 0.5 NoMirror NoClamp
E Corrupt 4x0.1 0.5 NoMirror NoClamp
F Corrupt 4x4 0.5 NoMirror NoClamp

OK, So this ones wierd, it does both Vert and Horiz.
Every Block of 4 decreases Horiz By 2 (and when switched to red which is x2 (32x32 as uposed to 16x16) in size it went down x4)


So, Correct Values for this would be 3, 7, B, & F where F is more correct to keep 'Square'

Also, these are refered to in Docs as "Shift"

==========

C0 0 B B x 0 1 F 8 001 2CF
0 OK 16x32 0.5 NoMirror NoClamp
1 OK 16x32 0.5 NoMirror NoClamp
2 OK 16x32 0.5 NoMirror NoClamp
3 OK 16x32 0.5 NoMirror NoClamp

4 OK 16x16 0.5 NoMirror NoClamp
5 OK 16x16 0.5 NoMirror NoClamp
6 OK 16x16 0.5 NoMirror NoClamp
7 OK 16x16 0.5 NoMirror NoClamp

8 OK 16x4 0.5 NoMirror NoClamp
9 Corrupt 8x2 0.5 NoMirror NoClamp
A Corrupt 8x2 0.5 NoMirror NoClamp
B Corrupt 8x2 0.5 NoMirror NoClamp

C Corrupt 8x1 0.5 NoMirror NoClamp
D Corrupt 8x1 0.5 NoMirror NoClamp
E Corrupt 8x1 0.5 NoMirror NoClamp
F Corrupt 8x1 0.5 NoMirror NoClamp

So, This deals solly with Vertical where each block of 4 repeats less.
Correct Value is dependant on previous scales or "Shifts" to keep the detail 'Square'
In this example the correct Value is 4,5,6 or 7

===========

C0 0 B B 8 x 1 F 8 001 2CF
0-F OK 16x4 0.5 NoMirror NoClamp

No Change with this value in either base or Detail

============

C0 0 B B 8 0 x F 8 001 2CF
0 OK 16x4 0.0 NoMirror NoClamp

Ok, this is odd, we might need to Nibble the last 2 digits too.
This Value seems to also be Lod_Frac starting at 0 and working up to about 0.25 at F
Thing thats odd though is that in all the other tests the value here was 1 and everything worked out fine, yet in this test 1 was working out at about 0.05 or something (Basicly replace)
Can you verify you changed the correct Nibble? 

==========

C0 0 B B 8 0 1 x 8 001 2CF

Odds = +0.5
Evens = 0

C0 0 B B 8 0 1 F x 001 2CF

each increment = 0.03

So, the last 2 are linked by 1 bit on 'F'

so, for best results the one that should be default is S=1111 T=1111 (3FC) giving each base texel 4 detail texles while 1110 1110 (BB8) will give 8 texles per texle but depending on detail texture could result in slight moiring espesually at low min_levels (less than 0.75).
