预览

Here you will find various previews that let you check the effect of a Material Node and its effect on the overall material. The Node Preview area shows the result of the Node’s effect. This can, for example, be a noise pattern for a self-generating Node. Other Nodes require input in order to produce a result. For such Nodes, the Node Preview will display what the Node calculated using the input information. The Material Preview displays the material that is produced in the end. Both the effect of the Node or the result of its calculation and the effect this Node chain has on the final material can be compared with each other.

在这里你可以找到各种预览，让你检查材质节点的效果和它对整体材质的影响。节点预览区域显示节点效果的结果。例如，这可以是一个自生成节点的噪声模式。其他节点需要输入以产生结果。对于这样的节点，Node Preview 将显示 Node 使用输入信息计算的内容。材质预览显示最终生成的材质。节点或其计算结果的影响以及节点链对最终材质的影响都可以相互比较。

Right-click on the Preview to change its size – ranging from small to huge. Note, however, that a larger Preview also takes longer to update. In the same context menu you will also find the Preview HUD option, which can be used to enable or disable the HUD display text for the Preview. The left Preview shows the Node and the material is shown at the right.

右键单击“预览”更改其大小——从小到大不等。然而，请注意，更大的预览版也需要更长的时间来更新。在相同的上下文菜单中，你还可以找到预览 HUD 选项，它可以用来启用或禁用 HUD 的预览显示文本。左侧预览显示 Node，右侧显示材质。

The Preview of Material Nodes can also be defined globally via the Preferences menu’s Material menu.

材质节点的预览也可以通过首选项菜单的材质菜单全局定义。
