Hi, I’m working on a book animation in which the pages are led by multiple morph targets, switching from one to the next in the animation, however when the book is completely open one of the pages turns black. By turning on the vertex normal visualization I noticed that the normals gradually rotate to one side until they are completely inverted. I already tried everything, I enabled skin cache in the project settings, checked recompute tangents in the lod and more but nothing solves it. I would be extremely grateful if someone could help me. I will link the compressed fbx file below. Thank you.
