纹理坐标为物体的情况下下,图片纹理映射选择为球形,出来的外观比较奇怪,极点位置偏离中心,也不在物体顶点上。XY位置移动0.5才能回正,不知道为什么blender这样设计。 补充: 纹理坐标为物体。贴图选择为方框、剪辑。可以看到纹理原始的坐标系在如图位置,模型的纹理坐标系原点在中心。纹理的原始坐标系都是一个原点在顶点上...

blender的shading界面是渲染的工作原理——从input开始经过各种着色节点(shading node)的变换变成output。现代渲染可以是光追计算,通过光线函数和物体顶点的交点和法线计算等进行完全模拟自然光的渲染,也可以是blender那样顶点对应贴图然后用shader一层层渲染获得想要的效果。 https://www.youtube.com/watch?v=mbCibu2isB8...
需要用NODE来实现：如下图粗红线所示（有了细红线的NODE 你所看到的默认选项就消失了，删除它，又会出现）

Game engines commonly use two texture coordinates, U and V, for mapping the width and height of a texture. A third axis W can also be used for depth if you are using a 3D volume texture, but usually this coordinate is removed for efficiency. ...

Cage has two meanings in the normal-mapping process: a low-poly base for Subdivision Surface Modeling (usually called the BaseMesh), or a ray-casting mesh used for normal map baking. This section covers the ray-casting cage. Most normal map baking tools allow you to use a distance-based...

UV transforms (also called texture transforms) would be something like this, if the values on the Mapping node are customized: Even when you are exporting the textures from Blender, those are only supported in three.js with some major caveats, so ignoring it might be best. :) Owner mrdoob...
