Essential LightWave 3D- P7

Essential LightWave 3D- P7: What you have in your hands is, quite simply, a collection of tools and techniques that many professional LightWave artists use every single day doing what we do in our various fields. The tools and techniques explored in this book are essential to creating the caliber of imagery that you see on film and television and in print and video games. | Chapter 5 Segment by Part does the same thing but with the polygon groupings parts you ve got set up. An odd thing with atlas maps is that on the map itself not every polygon has points to drag around. When two or more polygons share a point only one polygon has that point represented on the atlas map This would mean trouble when tweaking an atlas map or laying one out by hand if it weren t for Unweld. Detail Points Unweld takes any point shared by more than one polygon and breaks it apart into as many exact copies as there need to be so each polygon owns one of the copies. After using Unweld on a selection no one point of that selection is owned by more than one polygon. So after doing this forget about using Select Connected until you reunite all the points again. Note After using Unweld to tweak your UV map you use Detail Points Merge Points with the Range set to Automatic to re-fuse all the points that are in exactly the same position. This could cause smoothing problems where the surfaces of a Boolean operation meet and you have purposely not merged those points . If you know you re going to want to make an atlas UV map for an object that for whatever reason has points sitting exactly on top of one another and they need to stay that way set these points as part of a Point Selection Set so you can unweld them again after merging everything back into one piece after adjusting your atlas map. Figure 5-68 After having used Unweld the faces of the cube can be moved rotated scaled and generally pushed about so you get the exact look on your object you are trying to achieve. How do the default settings for creating an atlas map work for something complex like a character Not too well for this artist s tastes. Here is a quick and simple way I would set up Wolfie s head for an atlas map 1. Load Objects Chapter05 Cartoon-WolfHead.lwo. 2. Select Merge Points Automatic just to see if there are any points lying exactly in the same space that we will need to watch out for .
