Today, we're bringing you information about even more of the new features coming soon to LightWave v9 in its first free upgrade. If you just can't wait to start using these new features, never fear, you don't have to. Registered owners of LightWave v9 are invited to participate in the Open Beta program going on right now. Simply login to your product registration account at http://register.newtek.com and click on the Open Beta banner for details.

Material Shaders

When the Node Editor was introduced in LightWave v9, it paved a new way to quickly create customized surfaces. The Node Editor has been developed even further for LightWave with the introduction of the Material nodes, which duplicate real surfaces.

The Material nodes combine features of existing nodes into a more convenient and easier to use node system. The Material nodes duplicate specific surfaces, but can still access the power of the node system. Several types of material nodes are available.

Dielectric is a glass and liquid shader and is physically accurate, using Beer’s law. (Not that Beer!) Beer’s Law is about energy absorption, which occurs when light passes through a surface. The more light that is absorbed by the material, the darker it will look.

If you have a glass and look at the sides, you may notice that it is darker along the edges. It has the same transparency throughout, but it is relatively thicker along the edge, so more light is being absorbed or refracted.

Conductor is a shader node for physically accurate metal, making creating realistic metal surfaces easy with just a single node.

Sigma is another material node which uses subsurface scattering.

Nodes are also available for creating your own custom Material shaders, including a Standard node based on the Surface input node and a Material Mixer node for combining different materials.

Anti-aliasing

One of the major new technology revisions in the upcoming LightWave update is the new antialiasing technology. Aliasing is the stair-step effect you may have seen on a computer-generated image when two different colors are adjacent. This is due to the nature of pixels being rectangular.

Anti-aliasing is used to correct this stair-stepping effect. LightWave will introduce a new technique of anti-aliasing using a single pass to correct for aliasing. Previously, upon alias correction, a render pass was performed for each anti-alias level.

Another improvement includes new sampling patterns, which is the pattern of detecting rays used in the render. In the past LightWave used a fixed-sampling pattern, which tends to result in the tell-tale aliasing. The new Blue Noise is a random-sampling pattern. For a given pixel, Blue Noise will sample a semi-random point on the grid for a ray, which will be a minimal distance away from each other random sampling point. The sampling continues until the difference between two points are within a certain threshold or the maximum number of samples has been reached.

Adaptive Sampling is another improvement coming to LightWave, which will render the image in multiple passes. The first pass will render with the number of anti-aliasing samples you have selected. Each pass after that doubles the number of samples and only the pixels that exceed the Adaptive Threshold will receive additional sampling during each pass.

Thanks Kurtis.

This got me thinking though...As new materials gets created, will NT be releasing these like the way we get free textures as a Member Freebie? Cause that would just be awesome. Well thanks again NT.

They're nodes, so anyone could write them. I suspect Denis Pontonnier will probably the first to have a few materials out the door for us.


He Who Thinks We'll See Some Pretty Wicked New Nodes.

You are too much kind with me, Dave,
I think Antti Järvelä is the first, not me...

Denis.

These renders were created by Jonas and Antti.

We will be releasing surface presets from time to time, and we've created a section of the forums specifically for users interested in creating and sharing nodes: http://www.newtek.com/forums/forumdisplay.php?f=206

Denis.Well, he's the developer of the node system. I was referring to third party nodes, which you're only outdone by IFW.


He Who Doesn't Remember Seeing So Many Plugins Developed So Fast Before.

I flat out LOVE that Edited line on this one, Dave.

And yes, Denis, you and Richard are the BEST at this. You, though, are a bit more public about your process. Kudos and thanks!

Nothing for Modeller? I thought there was at least one new feature/improvement being trailed for 9.2 at some stage.

I downloaded the beta 9.2 Monday. I called and got the unlock numbers. The problem is the unlock was goob for three days. I called NT back and customer service said the beta expires Today, Friday. I ask if the non beta was being released and they could not answer. The question is does anyone know the release date and is there another beta being released?

I don't use LW intensively enough, or with enough knowledge in most aspects, to add anything useful as a beta tester - I was just surprised, and a little disappointed, at the (apparent) emphasis on Layout. I'll just take your post as a good sign for the release version when it's ready :)

you don't have to be!..i'm not..i just cruise round and see what everyone else is doing...they'd just want people to 'use it'...your not requested to submit notes etc...so no big deal there..go try it if you have 9.0 already.:thumbsup:
