Instance color
The Instance Color texture is used to hold an image and prepares each pixel of the image to be mapped to geometric instance IDs.
Octane Plugin is able to generate instances of an object and can also assign an ID to each of the instances generated such that number of instances results in a grid instance IDs. Colors can then be assigned via texture to each instance ID, in this case with an image in the Instance Color texture, matching the IDs with pixels of the image starting at the bottom left in row major order up to the top right.
实例颜色
实例颜色纹理用于保存图像，并准备要映射到几何实例ID的图像的每个像素。
Octane插件能够生成对象的实例，并且还可以将ID分配给所生成的每个实例，以使实例数量产生网格实例ID。 然后可以通过纹理将颜色分配给每个实例ID，在这种情况下，实例颜色纹理中的图像将ID与行主要顺序的左下角开始到右上角的图像像素匹配。

INSTANCE COLOR FROM FILE
1- First create a cylinder object and change its properties as shown in the picture.
文件中的实例颜色
1-首先创建一个圆柱对象，然后更改其属性，如图所示。
2- Then create a Cloner object and assign the cylinder object to the Cloner. Change the cloner settings as shown in the image below.
2-然后创建一个Cloner对象，并将圆柱对象分配给Cloner。 如下图所示，更改克隆器设置。
3- Next is the Material and Instance Color Setup. First create the Diffuse Material. Then open the Node Editor and drag and drop the material you created into the Node editor window. Drag the Instance Color directly to the node editor from the menu on the left. Now, when Instance Color Node is selected, connect the tiny yellow spot on the upper right to the Diffuse channel of Material. Now select any image file with 10x10 pixel size from the menu on the right and load it. After the Material Setup, Assign it to Cloner Object. In the picture below you can see the material and Instance Color setup.
3-接下来是“材质和实例颜色设置”。 首先创建漫反射材质。 然后打开“节点编辑器”，并将创建的材质拖放到“节点编辑器”窗口中。 从左侧菜单将“实例颜色”直接拖到节点编辑器。 现在，当选择“实例颜色节点”时，将右上方的小黄点连接到“材质”的“漫反射”通道。 现在，从右侧菜单中选择任何10x10像素大小的图像文件并加载。 材质设置后，将其分配给“克隆对象”。 在下面的图片中，您可以看到材质和“实例颜色”设置。
4- If you have done everything properly, you will get a result similar to the following picture. As you can see, each pixel value of our 10x10 pixel sized image created Instance Color for our 10x10 grid cylinders in Cloner. The Instance IDs of 100 cylinders in Cloner were automatically generated. It’s just like the Shader Effector. However, this feature works effectively in smaller image files. For example, if your image size is 500x500 pixels, the 2500 Instance ID object to be created for this will most likely crash Cinema 4D. So, use it wisely.
4-如果您已正确完成所有操作，则将得到与下图相似的结果。 如您所见，我们的10x10像素大小的图像的每个像素值都为Cloner中的10x10网格圆柱创建了实例颜色。 “克隆器”中100个气缸的实例ID是自动生成的。 就像着色器效应器一样。 但是，此功能在较小的图像文件中有效。 例如，如果您的图像大小为500x500像素，则为此创建的2500实例ID对象很可能会使Cinema 4D崩溃。 因此，请明智地使用它。
INSTANCE COLOR from vertex color
In this example we will describe how Instance Color is made from a Vertex Color.
1- First create a cylinder object and change its properties as shown in the picture.
顶点颜色的实例颜色
在此示例中，我们将描述如何从“顶点颜色”制作“实例颜色”。
1-首先创建一个圆柱对象，然后更改其属性，如图所示。
2- Then create a “Plane” object and change its settings shown in the image below. After entering the settings, make it editable (Press C).
2-然后创建一个“平面”对象并更改其设置，如下图所示。 输入设置后，使其可编辑（按C）。
3- Now we will paint the vertices of the Plane object. Select Plane Object and then select the Point Mode.
Press Shift + C and select Paint Tool from the command menu.
3-现在，我们将绘制平面对象的顶点。 选择“平面对象”，然后选择“点模式”。
按Shift + C，然后从命令菜单中选择“绘制工具”。
4- Paint the vertex in any color and shape using the Paint menu. Do not forget to select "Vertex Color (RGB)" from the paint menu. Once the painting is finished, the "Vertex Color Tag" will be automatically created in the Object Manager, next to the plane object. You will then use this Tag as Instance Color.
4-使用“绘制”菜单以任何颜色和形状绘制顶点。 不要忘记从绘画菜单中选择“顶点颜色（RGB）”。 绘制完成后，将在对象管理器中平面对象旁边自动创建“顶点颜色标记”。 然后，您将使用此标签作为实例颜色。
5- Create a Cloner object and assign the cylinder object to the Cloner. We also need to define Plane, which we just created, as the object to which the cylinder clones will distribute. See the picture below for settings.
5-创建一个Cloner对象，并将圆柱对象分配给Cloner。 我们还需要将刚刚创建的Plane定义为圆柱体克隆将分发到的对象。 请参见下图进行设置。
6- Next is the Material and Instance Color Setup. First create the Diffuse Material. Then open the Node Editor and drag and drop the material you created into the Node editor window. Drag the Instance Color directly to the node editor from the menu on the left. Now, when Instance Color Node is selected, connect the tiny yellow spot on the upper right to the Diffuse channel of Material. Now it's time to set the Vertex TAG. When Instance Color Node is selected, select Particle as Source from the menu on the right. In the Color Source section, drag and drop the Vertex Color TAG of the Plane objet. After the Material Setup, Assign it to Cloner Object. In the picture below you can see the material and Instance Color setup.
6-接下来是“材质和实例颜色设置”。 首先创建漫反射材质。 然后打开“节点编辑器”，并将创建的材质拖放到“节点编辑器”窗口中。 从左侧菜单将“实例颜色”直接拖到节点编辑器。 现在，当选择“实例颜色节点”时，将右上方的小黄点连接到“材质”的“漫反射”通道。 现在是时候设置“顶点标记”了。 选择“实例颜色节点”后，从右侧菜单中选择“粒子”作为“源”。 在“颜色源”部分中，拖放“平面”对象的“顶点颜色”标记。 材质设置后，将其分配给“克隆对象”。 在下面的图片中，您可以看到材质和“实例颜色”设置。
7- If you have done everything properly, you will get a result similar to the following picture. As you can see, the cylindrical objects were colored by the vertex color Tag of the plane. Although it is not a very practical method, at least it gives you more control and flexibility. You can also work with more vertex counts. Remember that too much vertex will increase your cloner objects count and the system will slow down as usual.
7-如果您正确完成了所有操作，将得到与下图类似的结果。 如您所见，圆柱对象由平面的顶点颜色Tag着色。 尽管这不是一种非常实用的方法，但至少它为您提供了更多的控制和灵活性。 您也可以使用更多的顶点数。 请记住，过多的顶点会增加克隆对象的数量，并且系统将照常减速。

4- Now we will use Mograph in Scatter Object. To do this, first create a Random Effector from the Mograph menu and drag it to the Effector section of the Octane Scatter Object. Change the “Random Effector” properties as you see in the picture below. You don’t have to enter these properties exactly. You can change as you like the settings in the Transform and Falloff sections. For example, you can select "On" instead of “user defined” in the Color section, and you can create more colorful cubes. Or you can change the shape of the Falloff. It’s up to you.
4-现在我们将在分散对象中使用Mograph。 为此，首先从Mograph菜单中创建一个随机效应器，然后将其拖动到Octane Scatter Object的效应器部分。 如下图所示，更改“ Random Effector”属性。 您不必完全输入这些属性。 您可以根据需要更改“变换”和“衰减”部分中的设置。 例如，您可以在“颜色”部分中选择“开”而不是“用户定义”，并且可以创建更多彩色的多维数据集。 或者，您可以更改衰减的形状。 由你决定。
