UVs looking weird when using the solidify modifier I'm working on an animation of paper sheets.
I want to keep things very simple since I'll have to animate a lot of them and don't want to complexify things if I don't need to.
So my mesh is just a subdivised rectangle :



But when I use a solidify modifier (to give the sheet some thickness), the edges of my paper are getting weird :



which is not the case without the modifier:



Does anyone knows what causes this and how could I avoid it ?

Thanks a lot
Your flat mesh likely has smooth shading enabled, which only becomes visible once you give it thickness. In object mode you can select your object and applied flat shading by using Object > Shade Flat.
