I have a 3 LOD database and want to have Performer
ignore the highest LOD. For example, given a
database with LODs like:

   LOD 0 -> switch in = 17000, switch out = 0
   LOD 1 -> switch in = 34000, switch out = 17000
   LOD 2 -> switch in = 68000, switch out = 34000

make it behave as a 2 LOD database over ranges 0-68000
where the coarsets 2 LODs are utilized:
 
   LOD 0 -> switch in = ?????, switch out = 0
   LOD 1 -> switch in = 68000, switch out = ?????

I have tried setting the RANGEOFFSET and RANGESCALE
for a pfLODState and calling pfChannel::setLODState but
my offset and range factors appear to be wildly off.

What am I missing here?

Will
