I got all the way through to the end of the lesson, when I had created the material and texture to demonstrate the normal bake. When I clicked over to texture shading, the texture still looked like an older version of the texture (the one with high frequency baked in), and not the blue/pink texture. However, when I went to render mode, I could see that all the shading was accurate, and was outputting the correct results. Any ideas where I may have slipped up? Thanks!
