Essential LightWave 3D- P21: 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.

Using a render farm of only two machines (of equal processor speed and physical memory) will render your scene twice as fast as just one of the machines alone! Even if you only have one machine, you can queue a bunch of things to render and have LightNet set the CPU priority of the render node to Lowest, so you can still work while you’re rendering. LightNet is much Figure A-28: LightNet. easier to set up and work with 588

The full version ($19.95 + shipping) has Sherlock over 65,000 puzzles of each size. (Intel) Demo What it is: Sherlock is a game of logic — a lot like solitaire, only that with each and every puzzle you have the ability to be suc- cessful. Your own mental ability, not chance, is what determines whether you win or lose. What makes this cool: This simple game will help train you to see how solving even the most seemingly complex puzzles is simply a matter of doing what needs to be done in the moment — eliminating the impossible and slowly resolving your way to the solution. This is training for 3D — Figure A-29: Sherlock. and for life. Figure A-30: Sherlock. 589
  3. Appendix B Resources So, where do you go to find answers to the yet. Some are just too cool to not jump in questions you come across as you go about immediately and start scrounging around your work? There are many resources, both for neat bits and pieces that are the perfect online and in print. Some answer questions fit for the things you have zinging about in you may not even know you’ll be asking your creative mind! Community LightWave’s online community is without connecting people from around the world. If equal. Just as some are gifted in program- you aren’t sure where to find what you’re ming (as are the artist/programmers who looking for, or if you aren’t quite sure what have contributed to the wealth of material you’re looking for yet, these places can help described in Appendix A), some are gifted point you in the right direction. in teaching, organizing information, or NewTek One of the first places to go to find out “how” (as well as get updates, patches, and whatnot) is the NewTek web site. (Do you think this kind of community could exist for a package that doesn’t stand with its users 100%?) NewTek’s web site has collections of tutorials, links, and information about “who’s who” in the LightWave community. Check it out! Figure B-1: NewTek web site. 590
  4. · · · · · · · · · · · · · · · · · · · · · · · · Re s o u r c e s Flay Flay is also a “first stop” for finding out just about anything that exists concerning LightWave. Here you will find up-to-date listings of news, jobs, tutorials, tips, and of course, my personal favorite: plug-ins. Each category is searchable so you can quickly find exactly what you’re looking for. Figure B-3 shows Figure B-2: web site. the plug-ins page, list- ing the latest 20 plug-in “spottings” and sporting a search engine that will find what you’re looking for, even if you don’t know its name — only what you want it to do for you!

  5. Appendix B · · · · · · · · · · · · · · · · · · · · · · · SpinQuad SpinQuad is one of the leading LightWave forums on the web. Founded by industry legend William “Proton” Vaughan and populated by some of the most established LightWave users in the world, it is an excellent place to meet professionals, get answers to your ques- tions, and hone your skills. With its friendly, small-town feel and an unwavering commit- Figure B-4: SpinQuad web site. ment to the user and his art, SpinQuad perfectly embodies the spirit of the LightWave community. CgTalk CgTalk is the world’s largest forum for com- puter graphics professionals. With almost 100,000 mem- bers, it offers support for nearly every major graphics application. Visitors can find focused critiques, contests, industry information, jobs, and, of course, dis- cussions on more than a dozen 2D/3D applications. Figure B-5: CgTalk web site. 592

Born out of a desire to extol the powers of LightWave over Maya, the site now includes users of every 3D applica- tion. Members participate in a variety of challenges, ranging from several minutes to several hours in length. The idea is to work quickly toward your goal and produce better work than your competitors within the time allowed. If you really want to hone your skills, I highly recommend a workout at 3D Fight Club. Figure B-6: 3D Fight Club web site.

Appendix B · · · · · · · · · · · · · · · · · · · · · · · TUCOWS I had just sort of assumed that most people already knew about TUCOWS as the ulti- mate place on the net to download reviewed software for almost any and every com- puter platform. But I have found that a lot of people are still unaware of it. Plain and sim- ple, it is the best place to search for programs you need, whether they be games, OS “fine-tuners,” network “stuff,” emulators, or whatever (IMHO). Almost every package is reviewed and scored in “cows” (five cows being the highest score). You can even super search on the kind of license agreement the package has (com- Figure B-8: TUCOWS web site. mercial, shareware, freeware, etc.). Commercial While the quantity of free materials avail- from providers who have spent countless able on the net is astounding, nothing can hours developing materials to assist in the match the quality of dedicated commercial development of your skills and abilities. products. The following resources come Kurv Studios per hour, making them one of the most cost-effective sources of training you’ll find. Kurv Studios burst onto the scene in 2004 and has quickly become one of the leading suppliers of high-quality com- puter-based training material. Their LightWave series is hosted by indus- try-recognized artists and offers training on nearly every aspect of the software. But what makes Kurv Studios really stand out from the competition is not the quality; it’s the price. Videos from Kurv Studios typically range from $24.95 to $49.95 and contain more than 10 hours of training material. That’s less than $5 Figure B-9: Kurv Studios web site. 594

The images range from male to female, young to old, clothed and nude. There are ref- erences for facial expressions, body poses, and even suggested poly-flow. If you’re planning on developing 3D characters, a membership to this site should be considered essential. For less than $10 you can gain access to nearly 10,000 high-res images. If Figure B-10: web site. you’ve looked at the price of stock photos or the labor involved in hiring your own ref- erence model, you’ll quickly see why is an invaluable resource at an unparalleled price. HDRI 3D HDRI 3D is definitely worth tak- ing a look at. Each issue is filled with an amazing number of high-quality tutorials and articles on subjects from texturing and hair and fur shading to vehicular modeling and building city- scapes. It doesn’t just touch on the “tried-and-true” uses of LightWave. The issues I’ve seen have also explored some really neat applications that I don’t imagine a lot of people have Figure B-11: HDRI 3D magazine web site. thought of — yet! 595
  9. Appendix B · · · · · · · · · · · · · · · · · · · · · · · Worley Laboratories Worley Labs is the company that contributed the Lite version of their Sasquatch Hair/Fur Shader to LightWave 7+. They also have two collections of very useful plug-ins bundled under the names Taft and Polk (yes, just like two former U.S. presidents). The really cool thing they’ve just come out with is the FPrime pro- gressive rendering system. FPrime provides you with “real-time F9” rendering, allow- Figure B-12: Worley Labs web site. ing you to see changes to surfaces, lights, cameras, objects, etc., in real time.

These products are RealFlow and RealWave. They create some of the best simulations of fluids (large and small) I’ve Figure B-13 seen, and their fluid dynamics simulations equal work done on Houdini versions of the software are available for (which costs many, many, many times download from their web site. more).
