Blend 节点描述

使用 Mode 参数定义的混合模式将输入 Blend 的值混合到输入 Base 上。指混合的强度由输入 Opacity 定义。Opacity 值为 0 将原封不动返回输入 Base。

端口名称方向类型绑定描述 Base 输入动态矢量无基础层值 Blend 输入动态矢量无混合层值 Opacity 输入 Float 无混合强度 Out 输出动态矢量无输出值控件名称类型选项描述 Mode 下拉选单 Burn、Darken、Difference、Dodge、Divide、Exclusion、HardLight、HardMix、Lighten、LinearBurn、LinearDodge、LinearLight、LinearLightAddSub、Multiply、Negation、Overlay、PinLight、Screen、SoftLight、Subtract、VividLight、Overwrite 要应用的混合模式生成的代码示例
