Displacement Blender 置换混合

Introduction

引言

This shader allows you to blend the results of up to 4 displacement mapping shader nodes. It is essentially a displacement equivalent of the bump blender shader.
The output of this shader is a displacement vector, which when attached to the material displacement input will result in a perturbed surface and normal.

这个着色器允许你混合最多4个位移贴图/着色器节点的结果。它本质上是一个位移相当于凸点搅拌器着色器。这个着色器的输出是一个位移，当连接到材质位移输入时，会导致表面和法线受到干扰。

Base

基地

Input

输入

This is the displacement vector for the base layer of the material.

这是材料基层的位移。

Layer 0, 1, 2

0,1,2层

Input

输入

This is the displacement vector for a subsequent layer of the material.

这是材料后续层的位移。

Blend Weight

混合重量

This is a scale that is applied to the displacement vector, to control the 'strength' of the displacement.

这是一个适用于位移的尺度，用来控制位移的‘强度’。

Additive Mode

附加模式

By default the blending method for layers is that they 'take' from the previous layers and so on. For example, if Layer 0 had a 'Blend Weight' of 1.0, the base layer would contribute nothing, leaving only Layer 0's displacement contribution. This option allows you to disable that blending rule and just add the subsequent layers.

默认情况下，图层的混合方法是从前面的图层中“取出”，依此类推。例如，如果0层的“混合重量”为1.0，那么基层就不起作用，只剩下0层的位移作用。此选项允许您禁用混合规则，只需添加后续图层。
