I'm new to Blender and following along with the Blender Guru's tutorial series for beginners, where you make a doughnut and coffee. I've been doing everything He does step by step. In Part 4 Level 2 of the series, he adds a Noise Texture. In the video it works just fine for him, but when I do it, my mesh (the doughnut) turns pink indicating a problem. I have gone back and retraced my steps several times and I can't figure out what's wrong. I'm using version 2.82.7.
Can someone please tell me where I went wrong?
