Hi Terry,

This looks like a pfb-loader/writer problem.

Could you compare the outputs of pfPrint after loading the .flt
and after loading the .pfb models.. Can you see any difference
which may explain your problem?

Also, you may want to play around with loader-specific settings.
(look at man pfdConverterMode_flt and pfdConverterMode_pfb)..
You can try enabling/disabling optimizations in the flt loader, the
pfb writer, and the pfb loader.. can you find any configuration of
such settings that eliminates your problem?

Can you reduce the size of your .flt model and still reproduce
this problem? If you can, you may be able to isolate a small
portion of your db which is causing the problem..

Hope this helps a little.

Ciao,
Paolo

When running the .pfb version some of my textures periodically vanish leaving plain white terrain. Sometimes the textures vanish for long periods and sometimes they flash on and off with a period of about 1 second. Anyone know anything about this problem?
