Just ran into this again so I thought I'd submit it. This error is present in
every version of the Shader Bible, including the one distributed with the
editor and online at qeradiant.com. (BTW, if you go to gtkradiant.com, there
is no "Users Manual" link in the sidebar... probably should be.)
So... in the part on tcMod transform, this equation is shown:
T' = t * m01 + s * m11 + t1
The first two constants are switched; it should really read
T' = s * m01 + t * m11 + t1
