Will,

I just had a very brief look at your bigPatch macro.

And I wonder if you forgot some parenthesis in these two
statements:

#local dX = toPt.x-fromPt.x/Cols; 
#local dZ = toPt.z-fromPt.z/Rows;

I suspect that it should be like this:

#local dX = (toPt.x - fromPt.x)/Cols; 
#local dZ = (toPt.z - fromPt.z)/Rows;


Note that the link you gave in the readme.txt file does
not work:

If you are interested in getting an impression of how
(some) POV-people look at commercialized pov utilities,
then I recommend that you skim through this thread:
