unity材质球自动遍历所需贴图
一、原理
二、用法
- 1.代码：
- 2.使用方法

一、原理

例如一个材质球名为：decal_text_cranes_01_mat ，
然后从全局遍历出：decal_text_cranes_01_albedo赋值给材质球的basemap,
全局遍历出decal_text_cranes_01_maods 赋值给材质球metallicmap通道，
全局遍历出decal_text_cranes_01_normal 给材质球normalmap通道，
**规律：**材质球名字：decal_text_cranes_01_mat 把后面mat换成通道名称，就是该材质球的通道贴图

二、用法

1.代码：

using unityengine;
using system.collections.generic;
using system.io;
using unityeditor;

public class autoassigntexturemaps : monobehaviour
{
    public list<material> targetmaterials; // 在inspector中指定目标材质列表
    private dictionary<string, string> texturemapnames = new dictionary<string, string>
    {
        { "albedo", "_basemap" },   // base color
        { "maods", "_metallicglossmap" }, // metallic and smoothness
        { "normal", "_bumpmap" }     // normal map
    };


    [contextmenu("_alphamat后缀自动补全")]
    void assigntextures1( )
    {
        foreach (material material in targetmaterials)
        {
            string basename = material.name.replace("_alphamat", "");
            foreach (var pair in texturemapnames)
            {
                string texturename = basename + "_" + pair.key;
                texture2d texture = findtexture(texturename);
                if (texture != null)
                {
                    material.settexture(pair.value, texture);
                    debug.log($"assigned {texturename} to {pair.value} for material {material.name}");
                }
                else
                {
                    debug.logerror($"could not find texture {texturename} for material {material.name}");
                }
            }
        }
    }

    [contextmenu("_mat后缀自动补全")]
    void assigntextures2( )
    {
        foreach (material material in targetmaterials)
        {
            string basename = material.name.replace("_mat", "");
            foreach (var pair in texturemapnames)
            {
                string texturename = basename + "_" + pair.key;
                texture2d texture = findtexture(texturename);
                if (texture != null)
                {
                    material.settexture(pair.value, texture);
                    debug.log($"assigned {texturename} to {pair.value} for material {material.name}");
                }
                else
                {
                    debug.logerror($"could not find texture {texturename} for material {material.name}");
                }
            }
        }
    }
    texture2d findtexture(string texturename)
    {
        string[] guids = assetdatabase.findassets(texturename);
        if (guids.length > 0)
        {
            string assetpath = assetdatabase.guidtoassetpath(guids[0]);
            return assetdatabase.loadassetatpath<texture2d>(assetpath);
        }
        return null;
    }
}
