I got another problem now, in the same tutorial but in page 93 (Tutorial) tells me to do this:
3 From the Status Line, select the Rendering menu set using the menu
selector.
The main menu changes to display the menu set for Rendering.
4 From the main menu, select Lighting/Shading > Assign New Material > Blinn.

I thought I did everything well, I changed the Blinn's color but the temple kept being grey, why is this?
Maybe I didn't selected something correctly.
I don't really know about the "select Lighting/Shading". Where can I select it?
