For example I have a paper mesh I want to bend it. how can I use material shader to do this ?
for any practical application id say materials aren’t the way to go. you’d normally have either a rigged paper model or have blend shapes/morph targets to make something fold or bend. that being said you could mask the paper with a gradient and then apply world position offsets or world displacement. the problem comes with the fact that paper bending is a rotation and not a translation that’s why bones/rigging would make more sense. anyway i hope that’s at least some help …
