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
