That isn´t true in all. Only u need change the materials... Raytracer need a loooooong time render. But u can change it to Vray or Brazil or standard, etc... I change some cars to Vray and others to brazil.
hey when I press "on run driving" the car are stoped.. I press all in the mouse and the keyboard and I got nothing... how move the car? How make the animation? I thing that the "tutorial" are incomplete.
