for untransformed external references it creates a pfGroup. for transformed
external references it creates a pfSCS. by default the loader calls pfFlatten
which would apply the SCS leaving it with an identity matrix. also by default,
the loader will clean the scene graph of unneccesary pfNodes. any identity
pfSCS's will be deleted.

>Is there any possibility to tell the loader or even perfly to do that.

# performer 2.x environment
# tell perfly and loader not to optimize the scene graph too much
# you will see all pfSCS nodes created by the loader
perfly -Q0 -y flt,1,0 -y flt,2,0 file.flt

Regards.
