Sometimes during VR playback people seam to disappear and then reappear, even though they are not moving between floors or on/off staircases?

This can happen when there are a large number of objects being viewed on the screen at one time, especially when using high detailed Avatars to represent the occupants. When this happens reduce the distancing point in the options menu or reload the simulation with low detailed Avatars. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
