I just purchased the Inkarnate commercial licence with Early access features. I had been making maps on it previously on the free portion. It is by the way completely free and no they are not crazy about not sharing maps etc. As it is, it doesn't seem like they care all that much about making sure you have a licence from them. Its 25 bucks for a year and real vague on what it covers but vague in the licencees favor it seems. It seems they are not really all that worried about it and to be honest it feels like more of a way to pad out your 25 dollars worth for access to the extra stuff. Which is higher resolution maps and objects and a much larger selection of stuff and ability to import custom textures.

I don't plan on making money off these maps but i did want the extra content so i went through the whole process. You email them.. they respond with a paypal invoice and a digital signature form that you submit and give back to them then they upgrade you.
