If you are targetting iR only, you should be creating geospecific clipmap
textures. Read the man page for pfcliptexture and pfimagecache for details on
how this works.
MultiGen will soon release our Series II Pro package which includes a texture
mosaic tool that is designed to create such large geospecific clipmaps, from
orthorectified source imagery, for use in Performer. Prototypes of this tool
were used to process the textures seen in the western United States flyover
demo shown at ITEC, IMAGE, SIGRRAPH etc :-) it saved us all alot of time.
Regards.
