一个three.js材质可以为凹凸贴图和纹理贴图分别设置重复值吗？ [英] Can a three.js material have separate repeat values for a bump map and a texture map?

问题描述

我正在尝试通过应用不太频繁重复的凹凸贴图来分解纹理中的重复。不幸的是，它似乎采用了'landTexture'的重复值（64），而不是我设置为（1）的值。

I'm trying to break up the repetition in my texture by applying a bump map which repeats much less frequently. Unfortunately, it seems to take on the repeat value of 'landTexture' below (64), instead of the value I set it to (1).

landTexture.wrapS = landTexture.wrapT = THREE.RepeatWrapping;
landTexture.repeat.set(64, 64);
bumpTexture.wrapS = bumpTexture.wrapT = THREE.RepeatWrapping;
bumpTexture.repeat.set(1, 1);
var m = new THREE.MeshPhongMaterial({map:landTexture, 
                                     ambient: 0x552811, 
                                     specular: 0x333333, 
                                     shininess: 25, 
                                     bumpMap: bumpTexture, 
                                     bumpScale: 1, 
                                     metal: false });

如果我注释掉 map：landTexture ，然后凹凸贴图比例是1.我能以某种方式混合这两个重复值吗？

If I comment out map:landTexture, then the bump map scale is 1. Can I mix these two repeat values somehow?

推荐答案

否。偏移和重复值默认为其中之一：

No. The offset and repeat values default to one of them:

// uv repeat and offset setting priorities
//  1. color map
//  2. specular map
//  3. displacement map
//  4. normal map
//  5. bump map
//  5. roughness map
//  5. metalness map
//  6. alpha map
//  7. emissive map

在您的情况下，这将是 landTexture 设置。

In your case, that would be the landTexture settings.

解决方法是修改纹理，或创建自定义 ShaderMaterial 。

The workaround is to modify your textures, or create a custom ShaderMaterial.

编辑：例外是光照贴图和环境遮挡贴图，每个使用第二组UV。这允许其他纹理比light / AO贴图具有更高的细节。

The exception is light map and ambient occlusion map, which each use the second set of UVs. This allows the other textures to be of higher detail than the light/AO map.
