Hi,
I have tried your suggestion and it did not help my case unfortunately. I still
get abnormal memory usage.
The external file references in the .osg file that was generated with osgconv
looks like follows and I assume that the loading of this file is not cached so
it gets duplicated. There are about 120 of these ProxyNode:s all pointing to
the same file. If I change the FileNameList to point to an object that is
smaller than this "birch_unit.flt" file then the terrain can be loaded but
still takes abnormal amounts of memory.
ProxyNode {
nodeMask 0xffffffff
cullingActive TRUE
ExtRefMode LOAD_IMMEDIATELY
Radius -1
FileNameList 1 {
birch_unit.flt
}
num_children 0
}
