Hi
Its the optimisation/flattening process when your file is loaded, the
optimisation is removing what it see as redundant nodes and states, this is
Generally a Good thing to have happen
You can disable this on the command line for Perfly, long time since I used
perfly, I think its some thing like '-Q 0' to turn it OFF, see the
Perfly source code to confirm this
Best Regards
Gordon

Subject: Re: [info-performer] Question related to the pfconv/perfly
utilities
Hi again Stace,
I've got another problem.
Example: I've made and object file containing two cubes with different group
names. When loading this with perfly i try to show the node tree.
The two object are grouped as only one. The only way i get to group them as
two is if i make an mtl file with two different materials. is there another
way (i don't wanna change the colour of the objects just to seperated them
when loaded)?
sorry for all the questions btw. i'd really like to not bother you with this
questions.
Leif Richard
