LightWave 9.6: NewTek's

Welcome to a Laptop Battery specialist of the Dell Laptop Battery

LightWave 9.6 adds a nodal material shader specifically to imitate clearcoat car paint. Instead of having to weigh different shaders and other surfacing tricks to get the 'look' of a car, LightWave users can use this node in the node editor hooked into the material, set the color and clearcoat color, and even add metal flakes of different size and color into the paint. It may seem like a minor thing, but LightWave sees a lot of use on car commercials and a clear and consistent way to make the surface they need quickly. As can be seen from the samples above, the Carpaint node looks better- and all that was done was adding it to the model and inserting the correct base color and making a very slightly blue clearcoat. While a bit slower in the render, the Carpaint shader is obviously vastly quicker to set up- the shader setup took with battery such as Dell Inspiron 8000 Battery , Dell Inspiron 8100 Battery , Dell Inspiron 8200 Battery , Dell Inspiron 8500 Battery , Dell Inspiron 8600 Battery , Dell Inspiron 8600M Battery , Dell Inspiron 9200 Battery , Dell Inspiron 9300 Battery , Dell Inspiron 9400 Battery , Dell Inspiron B120 Battery , Dell Inspiron B130 Battery , Dell Inspiron E1405 Battery less than a minute, while the earlier shader set represented hours of work and test rendering.

Post-process pixel filtering is now multi-threaded, speeding up rendering in scenes with heavy pixel filters (including LightWave's built-in lens flare and glow engine.) Handling is included for pixel filters not designed to multithread. This lets LightWave use multi-core and multi-processor machines more effectively, while still producing clean consistent results for rendering and animation.

The first thing you'll notice when installing LightWave 9.6 is an option in the installer to install an SSE2 optimized version of LightWave. Its been awhile since I've seen this kind of requester, and 9.5 did not have it, so I ran a quick test to see if there was any new optimization done between 9.6 and previous versions.

Using a reasonably complex LightWave scene, on the same system (Dell Precision 470, dual Pentium 4 Xeon running at 3.0 GHz) I did a test render under LightWave 9.6, 9.5 and 9.3.1. Scene settings were maintained between the three versions. The render time increased between 9.3.1 and 9.5, from 22m 45s to 28m 49s, and then went down significantly between 9.5 and 9.6, with the LightWave 9.6 render taking 16m 40s. The render statistics window showed the global illumination calculation taking almost half as much time under 9.6 as it did under 9.5, but its difficult to quantify these against the 9.3.1 results because 9.3.1 counts the time for the global illumination passes differently.

However, there were differences in the render between the three versions. Notice the darker shading in the flames on the 9.5 and 9.6 version, as well as the difference in the shading of the smoke of the 9.6 version. When moving between versions of a 3D software where changes have been made to the render engine, you should always make sure that your scene renders the same, or at least that the image it produces is still acceptable. LightWave 9.6 has had a lot of 'under the hood' work done to the render engine to improve speed but also to improve efficiency. 9.6 can get better quality from formerly 'low quality' settings than previous versions.

NewTek's LightWave 3D 9.6 is the result of the company's commitment to giving small upgrades to LightWave users during the development cycle, instead of just bug fixes. Since LightWave 9.0, they have released 9.2, 9.3 (with 9.3.1 bug fix release), 9.5 and 9.6, with the 9.5 and 9.6 six months apart. Since the release of LightWave 5.0 in 1995, intermediate releases ('.x' releases) for LightWave have been free while 'version' (6, 7, 8, 9) upgrades cost, instead of charging for every single update. The recent releases have been done with an open beta program, open to all registered users of LightWave 9. After an internal beta phase, it is let loose to the users to see what breaks, and small bugs that might ordinarily make it through to release get squashed much earlier in the beta phase. This also gives the users a chance to make suggestions on new features while they are being implemented, and gives the developers feedback on those new features during development instead of after release.

LightWave v9 is available now at the suggested retail price of US$895. LightWave v9.6 is the fifth free update available to registered LightWave v9 owners. Registered owners of LightWave 3D [v8 or earlier] are eligible to purchase an upgrade for US$395. Educational pricing is available. For more information, please visit http://www.newtek.com.
