Hi,
what operating system are you running on?

I have a very large imagery set (~1 million files). When running
VirtualPlanetBuilder 0.9.9, I am limited to about 482 -t imagery files
for a given vpbmaster command before I get "ERROR 4: Failed to open file
/mp2/osg/file482.tif" for each -t file listed after the 482nd file
listed in the script and the *.ive files are not created.
The command I am using is: vpbmaster --PagedLOD --geocentric --terrain
-e 30.00 20.00 1.00 1.00 -o 30_20.ive
Running with the -t option pointing to the directory results in the same
error.
The -t directory is what I also use normally.
I've just checked the dirs for a previous build and I have -t pointing
to a dir with 1900 files and it worked under Linux.
What do I need to open up to allow more files to be processed
per vpbmaster run?
Not sure there is a special option that will make it work. Maybe you can
try splitting the files into multiple dirs you pass to -t?
Secondly, a test of a small VPB database of 1.34GB of CADRG imagery
produced 14.941GB of *.ive files using VPB 0.9.7 in 23 minutes time.
The same test with VPB Version 0.9.9 produced 14.826GB of *.ive files in
32 minutes. I was not expecting the newer VPB to only produce a tiny
(<1%) amount of compression, while taking about 40% more time.
Furthermore, I'm perplexed that my resulting output files are 11 times
the input imagery (1m black and white Controlled Imagery Base). Using
the --compressed option made no difference to the resulting *.ive sizes.
I require all levels of detail, so expect some increase in database
size, but can anybody help me reduce this to a smaller multiple as I'm
running out of disk space! What do I need to do to turn on Heightfield
compression, for example.
Robert O talked about some new gz compression in a recent thread, so if
he could post the command line he used, that might help reduce the size.
