commercial and personal use is okay. 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!
