utilities
Hi Gordon,
Thanks for the help, but it still doesn't seem to be working. I've
attached the files i'm using. Also i've checked "perfly -h" to get a list
of possible input args for perfly. "-Q 0" stated in "perfly -h" should
_not_ "Flatten tree and remove empty nodes"...
This is the command i run:
perfly -Q 0 cubes.obj
Perhaps my .obj file is bad?
