Noise 【噪波】

Noise

The C4D Noise node proivides access to Cinema 4D’s “Noise” shaders. Recent versions of OctaneRender® added OSL versions of the Cinema 4D noises, which can be enabled in Live Viewer Settings > Cinema 4D Shaders tab. This is an experimental feature, and stability issues may occur, in which case this feature can be disabled (per the toggle in this tab.) That said, the Octane Noise node is a native tool and very efficient. For speed and reliability, the Octane Noise node is the better first choice, with the C4D Noise node as a fallback as needed. You can read what the C4D Noise Shader is and what it does in the Cinema 4D help file, or you can go to this link for further information.
C4D 噪音节点提供进入电影院4d 的“噪音”着色器。最新版本的 OctaneRender 增加了影院4 d 噪音的 OSL 版本，可以在 Live Viewer Settings > Cinema 4 d Shaders 选项卡中启用。这是一个实验特性，可能会出现稳定性问题，在这种情况下，可以禁用这个特性(通过此选项卡中的切换方式)也就是说，Octane Noise 节点是一个本地工具，非常有效。对于速度和可靠性，辛烷值噪音节点是更好的第一选择，与 C4D 噪音节点作为一个回退的需要。你可以阅读什么是 C4D 噪音着色器和它在电影院4d 帮助文件，或者你可以去这个链接获得进一步的信息。

HOW TO USE

如何使用
C4D Noise can be used in any node with “Power” and “Texture” slots. Below you will see a few examples of C4D Noise in use.
C4D 噪声可用于任何节点的“权力”和“纹理”插槽。下面你将看到一些使用中的 C4D 噪音的例子。

THE SIMPLEST USAGE 最简单的用法

Open the Node Editor and prepare the setup as seen in the image below. Here, the C4D Noise node is connected Diffuse channel of the material.
打开节点编辑器，准备设置，如下图所示。在这里，C4D 噪声节点是连接漫反射通道的材质。

C4D NOISE AS AN IMAGE MASK 作为图像掩模的 C4D 噪声

Open the Node Editor and prepare the setup as you see in the image below. Here, the C4D Noise is used as a mask for the “Image Texture” node. Of course, you could also use this setup using the native Octane Noise, but the C4D noise advantage is that you can use many noise types and moreover you can control them as you like.
打开“节点编辑器”，准备如下图所示的设置。在这里，C4D 噪声被用作“图像纹理”节点的蒙版。当然，您也可以使用本机辛烷噪声设置，但 C4D 噪声优势是，您可以使用许多噪声类型，而且您可以控制他们，因为你喜欢。

C4D NOISE AS A DISPLACEMENT MAP C4D 噪声作为位移图

Perhaps the biggest advantage of C4D noise comes out when using the Octane Displacement Texture. You can create almost infinite variety of displacements with the Noise type here. Open the Node Editor and prepare the setup as you see in the image below. This setup is identical to the one described in the “Baking Texture“ topic, except this time we used C4D noise instead of Octane’s noise texture.
也许 C4D 噪音的最大优势来自于使用辛烷位移纹理。你可以创造几乎无限的位移变化与噪音类型在这里。打开“节点编辑器”，准备如下图所示的设置。这个设置与“烘烤纹理”主题中描述的设置相同，只是这次我们使用了 C4D 噪声代替了辛烷的噪声纹理。

C4D NOISE AS A MIX AMOUNT IN THE MIX SHADER

C4D 噪声作为混合着色器中的混合量
Open the Node Editor and prepare the setup as seen in the image below. Here, the C4D Noise node is used as a mix amount for the Octane “Mix Texture”. Sema Noise used in this example as a Noise type. You can go to this link for information on using the Mix Shader.
打开节点编辑器，准备设置，如下图所示。在这里，C4D 噪音节点用作辛烷“混合纹理”的混合量。在此示例中用作噪声类型的 Sema 噪声。你可以到这个链接获得使用混合着色器的信息。
