ah Arnold, I see because fixing the instance shape after the cache applied has always happened for me when transferring to a new scene, its simple to fix and has always worked. normally Its just a pointer to which object to pick in a group.
Think we have had some luck in the past with exporting a model with the instance shapes & pointcloud inside, exported/cached in a certain way it does keep a link between scenes but can't remember the exact details as it was hit or miss when we found what works. someone might have a better memory than me... Cristobel! there does seem to be an invisible pointer or link that gets lost when loading caches into new scenes. its odd that specifying the instances after the cache applied should not work in Arrnold though as I'm fairly certain that you can do this. may be something else?
