Hi,
I will be doing a bugfix and updating for Blender 2.63/2.64 soon. If there are bugs (presently I am only aware of one) please tell me about them.
BTW the macro officially lives at the SW forum.

Solidsmack only carried it to generate traffic to their site I think.
This macro wont evolve into an addon, at least by my doing, because SW is a poor place to set up your scenes and materials, uvs particularly. Also SW is to be replaced by Catia lite in the near future, and further, it seems likely Octane will move away from using .obj come instances in a few months or so.
