cardboard flute - cardboard thickness I need to prepare a textured simple, plane of cardboard, made of a simple mesh plane but using only, for example, solidify and subdivision modifiers. The thickness I've made as a second material on the object's rim with transparency. In real - cardboard has empty spaces between waves and two planes - spaces that look like holes.





From the right angle, as a fake, it looks quite nice :P
But it's not a solution:
 
Unfortunately, this problem occurs when I try to use displacement...

Help ;)
(edit)
My intention is to fold the cardboard into a cardboard box during animation close-ups of the camera. The plane must be rigged and the edge of the cardboard looks photorealistic and unfortunately also in high resolution

Thank you all for the advice. Unfortunately, my intention is to fold the cardboard into a cardboard box during animation during close-ups of the camera. The plane must be rigged and the edge of the cardboard look photo realistic and unfortunately in high resolution
Single face displacement will only get you so far.
Just to illustrate.

Single face displacement

The image texture is used to "extrude" the original face.
Notice the incomplete rims, rough appearance, and high required geometry.
Faces: 1 000 000



Multiple Faces

Three faces on top of each other.
Displacement is used on the middle face only, to creating the wavy pattern.
Top and bottom faces have solidify modifier to add thickness.
Faces: 1000
