I have begun Chapter 13 and the same problem occurs again as in the previous ones. When opening the first scene: cellDivide_v01.ma, the usual message appears: "current rendering engine does not support Legacy Viewport".
Already announces that all the scenes of chapter 13 will happen the same.
Please look for a solution with the book's author for these problems.
Thank you very much.
Thanks for reaching out, Juan--Open your Maya preferences, and under the Display section change the Rendering Engine to OpenGL - Legacy...then restart Maya. That will allow you to select the Legacy viewport renderers.
