Hi,
Which white overlay are you talking about?
Where do you see the missing textures?
There is no "animation" scene available in the demo mode, or are you able to get around it? Only the default blowjob pose is available, and you are able to give her a blowjob in any way you want.
Character customization is endless thanks to the Vroid model support. Small fine tuning like the breast size can be done ingame.
