well I like to offer free stuff but I would like to be paid for it too. So i decided anyone can use it but if you going to make something and get profit from it then thats not allowed, unless of course I sold it to you.
Just like how you can get academic versions of software, only students can buy the software but they are not allowed to sell any of there work.
Same thing with this, you can use the plugin as much as you want for free, but if you make an image that took advantage of the plugin (and you gained profit from it) you will have to pay.
Iv’e never made anything thats ever been sold, so im all a bit new to it.
Sorry for any confusion
