As Enabled mentioned, you’re welcome to contact us in support. However, the authors and mods have pretty much covered all of the ins and outs regarding available licenses, and author exclusivity, so there isn’t much information that we could provide that they haven’t already.
We’re sorry if you’re disappointed by the lack of a “developers” license, but we appreciate your interest in our marketplaces.
If anyone wants to blow $399 of their author earnings, you could pick up a plenoptic camera (light-field camera)
OR you could put that $399 to even better use by paying it to me and I’ll draw a picture for you using crayons and stick figures.
I mean it’s really up to you, whichever is the better value.
*Note: image would not meet GraphicRiver or PhotoDune standards and could not be submitted as a sellable file, even though it would probably be the most incredible image ever captured on the back of a Chili’s paper placemat.
