then the ssgTweens will render their vertices in a position (colour, etc)
that's 40% of the way between the bank 2 and bank 3.

+You can also set the behaviour when the selected bank number is larger
+than the number of banks in the model. This tends to happen when you
+simply add some amount of to the bank selector each frame in order
+to keep the animation running forever:
+<pre>
+
+ ssgTweenController::setMode ( int mode ) ;

+</pre>
+'mode' can either be SSGTWEEN_STOP_AT_END or SSGTWEEN_REPEAT.
+The default is STOP_AT_END - where anytime the bank selector
+is larger than the actual number of banks in the ssgTween node,
+it is clamped to the largest possible number. If you choose
+REPEAT, then the bank number will be taken modulo the number of
+banks.
