I produce Blender add-ons and sell them for free and for a fee. 3DCG designer / modeler in Japan. Since the activity base is twitter,(My response will be faster on twitter) The only sales sites I use are "blendermarket.com", "gumroad.com" and "booth.pm". ■ Twitter: twitter.com/Bookyakuno ■ My Site  | 忘却まとめ : bookyakuno.com ■ Old Addon  - Github: github.com/bookyakuno/-Blender- ■ Portfolio: artstation.com/bookyakuno pixiv.net/member.php?id=14307758 ■ Support / E-Mail: info★bookyakuno.com
