Alright, I will not be using the asset. Honestly kinda weird that you're anti-open source when that doesn't necessarily change the license of your art, but I'll go another route. Thank you for your response.

Just to be clear, I'm not anti-open source, I actually love open source projects, the reason that my paid assets can't be used open source games is that the the raw asset is avaiable to anyone, and can be considered redistribute the files, which is against most licenses that I saw.
Wich that In mind, I'm considering pulling this from the license, because maybe that's discouraging people to using open source projects, I will reply to you if anything change.
Thank you for your response.
