Hi,
speaking with myself here...
I've narrowed the issue down further. This works:
int main()
{
osgDB::readNodeFile(...)
optimizer.Optimize(...)
osgDB::writeNodeFile(...)
}
The same code executed in a plugin loaded using dlopen() doesn't work (i.e. has
the missing VertexIndices and NormalIndices). On a mac, both variants work. Is
it possible that there is some sort of static initialization issue?
Cheers & thanks for looking at this,
Uli
