Specify normals set all vertex normals to point in a specific direction point normals make all vertex normals point away from an object clone normals clone vertex normals from another mesh. The orientation of a vertex normal affects how neighboring surfaces reflect light. Edit normals modifier 3ds max 2019 autodesk knowledge. Important technique 3ds max vertex color displacement patterns.
Script for 3ds max 2012 2020 which can edit vertex normals. A 3ds max toolkit for editing vertex normals to make creating hair and foliage easier. Normals are used to define which side of a face or vertex is considered the out side. Then will copy the normal of this vertice to the target. Weighted vertex normals or face weighted normals use the area of the face to tune the vertices normals. There are scripts out there that offer alternative normal calculation methods, such as the weighted normals script, see here for more info. The angle of reflection equals the angle of incidence. By default, normals are set so that reflection of light in 3ds max follows the rules of realworld physics.
The out side of a face or vertex is the side that gets rendered unless you are using twosided materials, or turn on the force 2sided option on the render setup dialog common panel common parameters rollout. Max has a pretty poor way to calculate vertex normals for its smoothing groups, resulting in visible shading artifacts on faces. Unlike others fwn scripts, this one considers coplanar faces like they were a unique big face. This script is a must have for medium polygon modeling. Implement a new vertex normal modifier weighted normals. Vertex normal information is quite fragile, perhaps you could store the resultant normals in a vertex colour or uvw channel as a backup. Every mesh can be divided into up to 7 layers and each normal layer can be calculated independently. It should be possible to make this a single, live modifier from max 2016 upwards itll need some rework in terms of mesh manipulation. Im envisaging issues with combining and chopping up meshes. If the master or target objects have a lot of vertices the process may be slow.
Introduction this maxscript generates weighted vertex normals for any arbitrary geometry. This script supports any topology and any chamfer type including. You may try the extra option for more precise normal placement but the default works fine. No dependecies on this script are added to scene files, so it is fully compatible for other users who dont have this script installed. For each vertex in target object the script will search the closer vertex in master object. Weighted vertex normals or face weighted normals use the area of the face to tune the vertexs normals.
