I know my opinion is not relevant nor significant, but is the only one I have
I think the fairest thing would be to distinguish two categories (either animated or static).
The first one would allow anything, post processing, camera mapping, anything. This would give freedom to people who have mastery in those facets and material to do so.
In another not be allowed material not generated by octane, which would involve people who either do not have the equipment / software needed or that could considered not to participate if having to do so under the same category.
I understand that the objetive is achieving the highest quality material but I think that both categories could get great works, but the problem is that if it is not bounded in some way and is given freely, some people will not participate or what worse, people who will feel cheated.
