The laptop consists of 2 objects. The main part and the lid. The Lid is parented to the main object so all you have to do is move/rotate the main piece. The lid also has a rotation constraint so you can easily rotate the lid open and closed and it wont let you over rotate it in either direction. Included are the 2 textures used for this model, which I made myself.. The keyboard and the screen. The screen material uses an emission material to give you accurate lighting conditions. The object is ready to render in both Cycles and also Octane Render. The .Blend is ready for Cycles, so just push render. If you use Octane stand alone, I also included the .orbx for the material group, just import this into Octane Render.
