I am trying to prevent attribute sharing (i.e. pfMaterial) when models are
loaded using pfdLoadFile.
I am looking for a global procedure that does not require sending specific
flags to each loader.
I have tried to create a new pfdShare structure and set it to the global
share (pfdSetGlobalShare) and the builder share (pfdSetBldrShare).
I figured this would allow me to load models without sharing existing
attributes.
I found that this did not prevent sharing, so I resorted to traversing the
loaded pfGeode and duplicating any pfMaterials that have a reference count.
This worked until Performer 3.2, and now I get a seg fault.
Can anyone suggest a more elegant way to load models without sharing
attributes?
Thanks,
