Powerful Unity Editor Extension
Some of you might ask : The model is made , Decompress the map first in the model settings , Just unzip the material ?
Certainly. , But now the problem is that the model has no mapping , Maps are in SP Made in , The exported maps are all separate maps , It will not be directly bound to the model
All in all , It's no problem for you to paste one by one on the shader , I think it's too painful , I have to post a model … Post a der.
Editor extension can solve many manual problems .
Look at the effect :
The shader will automatically match the map
Pay attention when matching maps :
The map name must be : The model name _ Shader name _ Map type
Property introduction
- Model path : Dragging the model will automatically identify the path
- Map suffix : similar _Albedo perhaps _Occlusion, Some students like to name it like this ,AL,AO, So open it and customize
- Export shaders : The directory where the model exists will be automatically created Material Folder , Models that do not unzip materials will unzip materials to this folder
- Set the material : Automatically match the map according to the name of the model and shader
SP Export process :
file - Export map - The configuration needs to be named like this
among :
- $project It is the present. SP Project name ( In less than )
- $mesh Is the model name
- $textureSet Is the shader name
Code Introduction :
Attribute here, you can modify the default suffix
[SerializeField]
public string m_Albedo = "_Albedo", m_Metallic = "_Metallic", m_NormalMap = "_Normal", m_HeightMap = "_Height", m_OcclusionMap = "_Occlusion";
Set the name rule here :objName + “_” + mat.name + m_Albedo, Can be modified by yourself
void setMaterialShader(string path)
{
Material mat = AssetDatabase.LoadAssetAtPath<Material>(path);
string[] allPath = GetObjPath("Texture2D");
for (int i = 0, len = allPath.Length; i < len; i++)
{
string filePath = AssetDatabase.GUIDToAssetPath(allPath[i]);
Texture2D t = AssetDatabase.LoadAssetAtPath<Texture2D>(filePath);
string objName = Path.GetFileName(modelPath);
objName = objName.Substring(0, objName.Length - 4);
if (t.name == objName + "_" + mat.name + m_Albedo)
{
mat.SetTexture(Albedo, t);
}
else if (t.name == objName + "_" + mat.name + m_HeightMap)
{
mat.SetTexture(HeightMap, t);
}
else if (t.name == objName + "_" + mat.name + m_Metallic)
{
mat.SetTexture(Metallic, t);
}
else if (t.name == objName + "_" + mat.name + m_NormalMap)
{
mat.SetTexture(NormalMap, t);
}
else if (t.name == objName + "_" + mat.name + m_OcclusionMap)
{
mat.SetTexture(OcclusionMap, t);
}
else
{
Debug.Log(mat.name+" Shaders cannot match :" + t.name);
}
}
}
Complete code :
This code inherits EditorWindow
So we have to put it in Editor Under the folder , Make revolving door And Camera controller Is the same , All use Editor Extension Technology
using System.IO;

using UnityEditor;

_window.Show();
