cannot get the bump and displacement setting to work

[mav3r1ck1981]

Hi Joe, hoping you might be able to help. Ive followed your excellent tutorial, and it works perfectly for me until the latter half of section 4.

i get the this section and add the subdivision surface modifier, i change the setting to bump and displacement and i press F12 to render the new image, and this is what happens:

Do you have any ideas what im doing wrong? im using Blender 3.6.2, and ive downloaded your example blend file, and mirrored your setting exactly.

Thanks in advance,

Paul
