commercial and personal use is okay. Hairstyle comes with preset bone groups, but please fix the bones to your needs and likes, thankyou. Do not resell hair preset and texture! YOU WILL HAVE TO UNZIP THE RAR FILE FIRST! To install hair preset into vroid stable version : 1. search %appdata% in your computers search bar 2. click AppData on the top before Roaming 3. Click Local Low 4. Find the Pixiv folder, click Vroid Studio!!! Make sure there is a space between vroid and studio 5. find your custom items folder, go to hair folder ( front hair, back hair, etc ) you might have to save a random hair in the hair category on vroid studio first! -ATTENTION: I WILL HAVE INSTRUCTIONS IN THE RAR FILE ON WHERE TO PUT THE FILES- 6. drag the hair file into the folder 7. reload vroid studio and it will be there! thanks for coming to my shop!
