Are you sure your PlanePick value does represent the exact number
of planes stored in your image data ?

Your PlanePick value of 7 (00000111) means that HEXA has 3 planes...

...but HEXA has only 2 planes. So the third plane to be drawn is the
memory following the second plane. Who knows what it is ?
This can be one of your problems, but I think you have others and
I need a piece of your code to understand more.
