MAYA VRAY 翻译教程

四叶草

VRAY Rendering Engine for Maya also provides it's own light nodes. There are two ways to create them. 1 Create> Lights 2. HyperShade
Maya的Vray渲染器提供有自身的灯光节点，有两种方法创建它们。1 Create> Lights 2. HyperShade

Below there're few images showing you vray lights. All light produce nice smooth and soft shadows (depending on subdivs value).
下面是一些Vray灯光类型的的展示效果图。所有的灯光都产生了柔和的阴影（根据细分的值）

Now let's take a look at render settings
现在让我们看看渲染设置。
GI
VRAY Engine calculates global illumination using two gi engine. You can play with IrrradianceMap, PhotonMap, BruteForce(QMC) or light cache. It means, you can choose any of this method in that two slots.
IrrMap as first engine and light cache as second - this is universal method of gaining a good GI, but if you are a mentalray user you'll probably say, where's the f... photon setting, no worry, if you choose PhotonMap as your secondary engine, you'll have ability to control number of traced photons. There's also photon subdivs value in light setting.
全局照明
Vray渲染器计算全局照明可以同时使用两个GI引擎。你可以使用IrrradianceMap, PhotonMap, BruteForce(QMC) 或 light cache。这意味着你可以选择这些方式中的任意两种。
将IrrMap作为第一引擎，light cache为第二引擎是普遍的方法，能够获得很好的GI效果，但如果你是一个mentalray使用者，你也许会问，哪里是f... photon设置，没错，如果你选择PhotonMap作为你的第二引擎，你将有能力控制被追踪的光子数目，常常在灯光设置里调节光子细分值。
AA
Under Image Sampler you'll probably find AA Settings. There are seven AA filter. People say that the CatmullRom can produce best results for viz. Play with this settings and chose best for you.
抗锯齿
在图象采样下，你可能会找到抗锯齿设置。那有7种过滤方式。提到CatmullRom这种过滤方式它能产生最佳的结果。选择最适合你的设置。

QUALITY
There's one fast way to increase quality and render time. Under DMC Sampler rollout, there's SubdivsMult, what it does? Increasing this value, affects all subdivs values in dof, motion blur, irradiance map, brute-force GI, area lights, area shadows, glossy reflections/refractions.
质量
有一种办法可以使质量和渲染时间得到平衡。在QMC采样面板下，有一个细分倍数，它是做什么用的呢？增加这个值，会影响所有的细分值自由度，运动模糊，光子贴图，强制GI，区域灯光和阴影，模糊反射/折射。

我还是新手，看来要好好学了！
