Workflow Example

工作流程示例

What we want to do: We want to animate a camera around an element in an outdoor landscape, which means that the object must be textured in two camera perspectives, and we will texture the object using Photoshop (this can also be done using BodyPaint 3D).

我们想要做的: 我们想要使一个相机围绕一个户外景观的元素动画，这意味着对象必须在两个相机的角度纹理，我们将使用 Photoshop 纹理对象(这也可以使用 BodyPaint 3D)。

This is how we will do it:

我们将这样做:

1. Create and position two cameras that will be used for the camera projection. We recommend that one camera be placed at the beginning and one at the end of the animation. Name the cameras "Camera 1" and "Camera 2", respectively. 创建和定位两个相机，将用于相机投影。我们建议在动画的开头和结尾分别放置一个摄像机。分别命名为“一号摄像头”和“二号摄像头”
   
   
   
2. Open the 打开Projection Man 数字绘景 Manager (main menu: Window / Projection Man) and double-click on the "Camera 1" camera icon. This sets the active view to the "Camera 1" (also, switch to "Photoshop" mode in the "Mode" menu). Next we will create a basic texture in this camera view: 管理器(主菜单: 窗口/数字绘景)和双击“相机1”相机图标。这将活动视图设置为“ Camera 1”(同时，在“ Mode”菜单中切换到“ Photoshop”模式)。接下来我们将在这个相机视图中创建一个基本的纹理:
   
   
3. Right-click on the landscape object and select 右键单击横向对象并选择New Projection Camera … / Coverage Render 新投影相机.../覆盖渲染.
   
   
   Note: 注意:
   Make sure that a directory path to the Photoshop application has been entered in the 确保 Photoshop 应用程序的目录路径已经在Preferences’ 偏好 Projection Man tab. 数字绘景标签
   In the dialog window that appears, leave all settings at their default values and deactivate the 在出现的对话框窗口中，保留所有设置的默认值，并停用Draw Edges 绘制边缘 option. Click on 选项。点击OK 好的. Cinema 4D will now render the scene as it is viewed through "Camera 1" as a Photoshop file (that will subsequently be edited in Photoshop), including alpha channel, launch Photoshop, opening the image in the application. Simultaneously, a new projection camera will be created and named after the texture file. .Cinema 4D 现在将通过“ Camera 1”作为 Photoshop 文件(随后将在 Photoshop 中编辑)呈现场景，包括 alpha 通道、启动 Photoshop、在应用程序中打开图像。同时，一个新的投影相机将被创建和命名的纹理文件
   
   
   Create a new layer and color the object. The "background" layer only there for reference. Save the file and switch back to Projection Man. 创建一个新图层，并为对象着色。“背景”层仅供参考。保存文件并切换回数字绘景
   
   
4. Right-click on each of the channel icons and select "Edit Layerset". A dialog window will open for each image layer. Select the top layer in each window. Make sure that 右键单击每个频道图标并选择“编辑层集”。将为每个图像层打开一个对话框窗口。在每个窗口中选择顶层。确保这一点Layer Alpha 阿尔法层 is selected in the "alpha" window. 在“ alpha”窗口中被选中
   
   
   This completes the camera projection from the first camera’s perspective. 从第一台相机的角度来看，这样就完成了相机的投影
   
   
5. Double-click on the "Camera 2" icon. The active view has now been set to that of "Camera 2". Right-click on the landscape object and select 双击“ Camera 2”图标。活动视图现在已经被设置为“ Camera 2”。右键单击横向对象并选择New Projection Camera … / Coverage Render 新投影相机.../覆盖渲染 (see #3 above). This time a texture from the angle of view of "Camera 2" will be rendered and automatically opened in Photoshop: (见上文第3项)。这一次，从“ Camera 2”视角的纹理将在 Photoshop 中渲染并自动打开:
   
   
   If you take a closer look at the background layer you will see that there are areas that have not been textured or where the existing texture is very distorted. Create a new layer and correct these areas. Save the image. 如果你仔细看一下背景图层，你会发现有些区域没有纹理，或者现有的纹理非常扭曲。创建一个新图层，并修正这些区域。保存图片
   
   
6. Now Right-click on both layers’ channel icons for the newly created projection and select "Edit Layerset". A dialog window will open for each image layer. Select the top layer in each window (multiple selections and the selection of entire layer sets is also possible). Make sure that 现在右键单击两个图层的通道图标为新创建的投影，并选择“编辑层集”。将为每个图像层打开一个对话框窗口。在每个窗口中选择最上面的图层(多重选择和整个图层集的选择也是可能的)。一定要确保Alpha Layers 阿尔法层 is selected in the "alpha" window (the painted layer will automatically be used as a mask, without having to manually create an alpha channel). 在“ alpha”窗口中被选中(绘制图层将自动用作掩码，而不必手动创建 alpha 通道)
   
   
   
7. Done. You can now switch to your original camera and travel around your landscape object without seeing any texture errors (areas not textured). If you should nevertheless notice any texture errors you can easily create an additional camera with a different angle of view and compensate for these problematic areas using camera projection. 完成。你现在可以切换到你的原始相机和旅行周围的景观对象没有看到任何纹理错误(区域没有纹理)。如果你仍然应该注意到任何纹理错误，你可以很容易地创建一个额外的相机与不同的视角和补偿这些有问题的领域使用相机投影
   
   
   

When working with Projection Man it is a good idea to undock the Attribute Manager window that is in the Project Info mode. This gives you a good overview of the textures used and their corresponding paths. More importantly, though, the "Reload Texture" button can be used to reload a texture that has been modified (and saved) in Photoshop.

当使用数字绘景时，取消项目信息模式下的属性管理器窗口是一个好主意。这样可以很好地概述所使用的纹理及其相应的路径。更重要的是，“重新加载纹理”按钮可以用来重新加载在 Photoshop 中修改(和保存)的纹理。
