Hello, I am using Rhino 6 in mac (Parallel window)
I faced Render display mode problem.
When I turn on render view mode every material becomes dark gray,
if I click a object it becomes to right materials and view.
but in this status if i move the view, it becomes again dark gray material.
I used default render display mode.
I dont know why it happens, cuz I used Rhino5 it works well.
