Face weighted normals fwn is a technique to improve shading for 3d models. Vnt aims to address that problem by giving the artist full control over vertex normals. It turns out, that all the normals were inverted, so in order to get around this problem, the normals of the mesh must be flipped. Is it only maya and 3ds max and the other highend autodesk packages. But i think that might not really be possible, since normals are so difficult to control and keep intact. Then will copy the normal of this vertice to the target. For a cube, each vertex actually has three normals depending on which triangle you are talking about.

This is solved by averaging the normals of the planes to face outwards from the tree. I was wondering if that is available in max in anyway, im trying to make.

You can display the normal vectors for selected faces or vertices by. You can convert most objects in 3ds max to editable meshes, but for open spline objects, only vertices are available, because open splines have no faces or edges when converted to meshes. Weighted vertex normals or face weighted normals use the area of the face to tune the vertexs normals. Move your topology to that vertex, using it as a guide point. The face normal is always perpendicular to the triangle face.
