Noise Texture does not work with my mesh 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?
Hello I was just googling the same issue with donut turning up pink and posted about it here and someone very wise informed me Material previews are only in EEVEE and not Cycles: https://www.reddit.com/r/blenderhelp/comments/mne2lf/displacement_bumps_not_displaying_properly_while/
I notice you might have the same problem as me - change your top right Viewport shading from Material Preview to Rendered. That is what Andrew had in his tutorial and I simply overlooked it.
it solved the issue for me, hopefully for you too!
