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
