The dress is dForce enabled and will not perform well without simulation. It includes many adjustment and style morphs to use before and after simulation. Many popular body morphs for Genesis 8 and 8.1 have been optimized to improve it's appearance, but most body morphs will work with the auto-follow technology.
All material presets are optimized for the Iray Render Engine.
Thanks for stopping by, and I hope you enjoy the Alya Gown!
