Hi, could be a number of things but I'd check your normal vectors are correct. Do you really need solid geometry here or would a two sided quad be enough? You could create a leaf shape in a modeling tool like blender and export to obj/fbx files. Or you could use the built in PlaneMesh and get the shape using a texture of a leaf using alpha to coverage (see the materials examples in Qt 3D for an example of this).
