I do remember, and some of the fantastic renders that you did.
I also seem to recall that you planned to offer this as a paid service.
Sorry that it did not work out that way for you, but thank you for providing the resources to the community!
These obj files, were they created with Houdini (or something like it, not that I know what it is, I just encountered it elsewhere on GH very recently)?
Do you know if these files can be used in other rendering apps? I'd be kinda interested in experimenting with them, but apart from a bit of PovRay a few years ago I haven't done much with anything.
