How can I add lines to rounded edges on a Subdivision-Surface (SDS) object?
如何将线添加到细分表面(SDS)对象的圆角边上？
Select the edges on the low-res mesh where you want lines to be added. Create a Selection tag to store the selection (Select / Set Selection). Assign a Sketch Style tag to the object if it does not have one already, and on its Lines tag, enable Edges. On the Selections tab, Drag & drop the Selection tag into the Edges box.
在低分辨率网格上选择要添加线条的边缘。创建一个 Selection 标记来存储选择内容(Select/Set Selection)。如果对象还没有草图样式标记，则为其分配一个草图样式标记，并在其 Lines 标记上启用 Edges。在“选择”选项卡上，将“选择”标记拖放到“边缘”框中。
I’m having problems with isoparms for a Subdivision-Surface object.
我有一个细分曲面物体的等臂问题。
Isoparms come with a number of limitations. For example, culling may not be accurate. With Subdivision-Surfaces, the best solution is not to use the Isoparm line type. Instead use Edge lines and create a selection for ALL the edges on the low-res mesh, then follow the same procedure as for the Subdivision-Surface’s rounded edges tip above.
等臂带有一些限制。例如，剔除可能不准确。对于细分曲面，最好的解决方案是不使用等臂线类型。取而代之的是使用边缘线并为低分辨率网格上的所有边创建一个选区，然后按照上面提示的细分曲面的圆形边缘相同的步骤操作。

I need help with my cartoon characters and have two questions for you: One, how can I smooth out lines? Two, which line types should I be using?
我需要帮助与我的卡通人物，并有两个问题为您: 第一，我如何平滑线？第二，我应该使用哪种行类型？
Here’s a tip for getting some extra lines in your sketch effects using the Angle modifier, and smoothing out the strokes to prevent that STRAIGHT sketch line style, especially on low poly objects. Check out these comparison images with and without Subdivision-Surfaces.
这里有一个技巧，可以使用角度修改器在草图效果中添加一些额外的线条，并平滑笔画以防止笔直的草图线条风格，特别是在低多边形对象上。检查出这些比较图像有和没有细分曲面。

The left moose in both figures was created with Fold lines only. This is the most commonly used line type for a hard-drawn style. It produces an okay effect, but for a rough sketch the lines are a little too accurate in their placement; an artist may have some other quick strokes to represent volume and structure for instance.
左侧的驼鹿在两个数字创造与折线只。这是硬绘样式最常用的线条类型。它产生了一个不错的效果，但是对于一个粗略的素描来说，线条的位置有点太精确了; 例如，一个艺术家可能有一些其他的快速笔触来表现体积和结构。
This is where the Angle line type comes in handy. To create the extra lines for the center moose, Angle lines were switched on with Min and Max set to 31˚ and 50˚ respectively (note that the model has a Phong angle of 60˚). For the center moose without Subdivision-Surfaces, you can clearly see the effect in the extra detail for the mouth and hooves, and the volume or structure of the moose being represented in the chest and stomach areas. The effect is more subtle for the Subdivision-Surfaces moose because the model has been subdivided so the angles in many areas that were detected in the low-res may no longer fit in the specified range.
这就是角线类型派上用场的地方。为了为中心驼鹿创建额外的线条，角度线被打开，最小和最大分别设置为31和50(注意模型的 Phong 角为60)。对于中心驼鹿没有细分-表面，你可以清楚地看到额外的细节的影响，为嘴和蹄，体积或结构的驼鹿被代表在胸部和胃部地区。对于细分曲面的效果更加微妙，因为模型已经被细分，所以在低分辨率中检测到的许多区域的角度可能不再适合指定的范围。
Last but not least is the addition of curves, which are to be found on the Sketch material’s Distort tab. For the right moose in both figures, the Curve Stroke option was enabled and Type was set to B-Spline (this type allows for extremely smooth flowing lines rather then straight angular lines). You can clearly see how the strokes for his stomach, armpit and muzzle are curved and smooth rather than straight and angular. In the case of the right moose with Subdivision-Surfaces, you can see that because of the smooth, simpler curves, settings such as overshoot used in this line’s material may shoot out in different directions as with the armpit and nostril.
最后但并非最不重要的是添加曲线，这些曲线可以在素描材质的扭曲标签上找到。对于右侧驼鹿在两个图形，曲线中风选项启用和类型设置为 b 样条(这种类型允许非常光滑流畅的线，而不是直线角)。你可以清楚地看到他腹部、腋窝和口吻的抚摸是弯曲和光滑的，而不是直线和棱角分明的。在使用细分曲面的右侧驼鹿的例子中，你可以看到，由于光滑、简单的曲线，设置，例如在这条线的材质中使用的超调，可能会向不同的方向射出，例如腋窝和鼻孔。
Using curved strokes, especially on a low-res mesh, can help eliminate that low-res feel but allow for sketchier lines then would be found on a smooth high-res mesh. This combination of a low-res mesh, angles, and curved strokes set to B-spline can help to produce a more natural — yet at the same time rougher — sketch effect!
使用曲线笔画，特别是在低分辨率的网格，可以帮助消除低分辨率的感觉，但允许粗略的线条，然后将在一个光滑的高分辨率网格上发现。将低分辨率的网格、角度和弯曲的笔触组合到 b 样条上，可以产生更自然的效果ーー但同时也更粗糙ーー草图效果！
How can I speed up the antialiasing?
如何加快抗锯齿的速度？
If you are using the Hatch shader or Spots shader with Cinema 4D’s Best Antialiasing (to ensure the texture is antialiased … ), switch the Antialiasing mode to Geometry and blur the hatch or spots texture using Blur Scale and Blur Offset.
如果你使用的是带有 Cinema 4D 最佳反锯齿效果的渲染器或斑点渲染器(为了确保纹理是反锯齿的...) ，切换反锯齿模式为几何图形，使用模糊缩放和模糊偏移模式模糊阴影或斑点纹理。
How can I get rid of unwanted lines?
我怎样才能摆脱不需要的线条？
Select the edges or polygons for the problem area and exclude them from line generation using the Sketch Style tag’s Lines box (Maps tab) and Exclude mode.
为问题区域选择边缘或多边形，并使用草图样式标记的线框(map 选项卡)和排除模式从线条生成中排除它们。
How can I get rid of opacity overlaps?
如何去除不透明的重叠？
On the Sketch material’s Render tab, set Self-Blend to Average. Try the Overwrite mode also. (Which mode is best usually depends on the texturing of the line).
在素描材质的渲染标签上，设置自混合为平均。也尝试覆盖模式。(哪种模式最好通常取决于线条的纹理)。
I have two patterns which overlap in places, how do I get rid of the overlaps?
我有两个重叠的地方模式，我如何摆脱重叠？
On the Sketch material’s Render tab, set Self-Blend to Overwrite. If one of the patterns disappears completely (center object), it has been overwritten by Sketch and Toon’s drawing order — to resolve, set the missing material’s Priority value (Sketch material, Main tab) higher.
在素描材质的渲染选项卡上，设置“自混合”以覆盖。如果其中一个图案完全消失(中心对象) ，它已被 Sketch 和 Toon 的绘图顺序覆盖ー为了解决，将缺失材质的优先级值(草图材质，主标签)设置得更高。
I’m having problems with a perfect sphere.
我在一个完美的球体上遇到了问题。
Convert the sphere to polygons. There are many limitations with perfect spheres!
把球体转换成多边形。完美的球体有很多限制！
I don’t like the random look Sketch and Toon has picked.
我不喜欢随机的外观，素描和图恩选择。
If the variations (such as clone, adjustment … ) are not as you would like, adjust the Variations Seed on the Sketch material’s Render tab. Disable the Static option if you wish these to change per frame.
如果变化(比如克隆，调整...)不是你想要的，调整素描材质渲染选项卡上的变化种子。禁用静态选项，如果你希望这些改变每帧。
Gaps are appearing in the lines. Why?
线条上出现了缝隙，为什么？
Check the polygons in the gap area. Although Sketch and Toon does its best to work with non-planar polygons, it is sometimes better to split them into triangles that give the correct surface you intend.
检查缝隙区域的多边形。尽管 Sketch 和 Toon 尽最大努力处理非平面多边形，但有时最好将它们分割成三角形，从而得到你想要的正确曲面。
I’m getting thin lines in the rendered image.
我在渲染的图像中得到了细线。
Use the Hidden Culling by setting it to either Scene or Children and so on. The fewer objects it has to cull against the better (e.g., Scene is slowest).
使用隐藏剔除设置为场景或儿童等等。需要筛选的对象越少越好(例如，场景是最慢的)。
Another cause of thin lines can be objects too close together; try moving them apart slightly. An example might be a belt around a waist, or ring on a finger. If the objects are very close, then the lines may cull.
造成细线的另一个原因可能是物体靠得太近; 尝试将它们稍微分开。一个例子可能是腰间的带子，或者手指上的戒指。如果对象非常接近，那么线可能会剔除。
