I like that it's free, open source (which means there are more options) It works with most VR headsets/cameras out of box; easy to use even if you don't have much experience in 3d modeling or renderingThe interface could be better at timesIt isn't very intuitive sometimes but once u get used everything starts working smoothlyEasy enough so anyone can pick up quickly! Nothing yetI really love how customizable this app makes my models look without having expensive programs installedThis also helps me save money as i'm not buying all these extra items just because they're needed by other people who need them too :) There aren't any problems thus farBut please keep improving your product!! This will help expand its reach greatly! And make sure before publishing an update always test thoroughly first!!
