function OnAssignMaterialModel ( : , renderer : Renderer) : Material


Feeds a source material

The returned material will be assigned to the renderer. If you return null, Unity will use its default material finding / generation method to assign a material. The sourceMaterial is generated directly from the model before importing and will be destroyed immediately after OnAssignMaterial.

class MyMeshPostprocessor extends AssetPostprocessor {

function OnAssignMaterialModel (material : Material, renderer : Renderer) : Material
var materialPath = "Assets/" + + ".mat";

// Find if there is a material at the material path
// Turn this off to always regeneration materials
if (AssetDatabase.LoadAssetAtPath(materialPath))
return AssetDatabase.LoadAssetAtPath(materialPath);

// Create a new material asset using the specular shader
// but otherwise the default values from the model
material.shader = Shader.Find("Specular");
AssetDatabase.CreateAsset(material, "Assets/" + + ".mat");
return material;
