Hi Gustav,
If you try to remove the texture by renaming it and the problem still
occurs, then the memory consumption is probably due to the vertices of
the tree. If you use external references over ProxyNodes nothing will be
shared concerning the vertices and this behaviour would be "normal".
Could be that the OpenFlight loader does not have this problem, as the
optimizer merges the scenegraph somehow and thus the problem disappears.
A solution might also be to use PagedLODs instead of ProxyNodes and to
not load all trees into memory at once. Might also be an option to add
the object to the scene and reference it (we call this "internal
reference").

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
}
