XNA How To: Draw a Model with a Custom Effect

Drawing a Model With a Custom Effect

When you load a Model, the model is set by default to use the BasicEffect. You can change this by customizing the content pipeline, or you can apply a newEffect to the Model when you load the Model.

To draw a model with a custom effect

1. In your game's LoadContent method, load your Model, typically using the ContentManager.

   C#

   terrain = Content.Load<Model>("terrain");
   

2. In LoadContent, load your Effect, typically using the ContentManager.

   C#

   MyEffect = content.Load<Effect>("CustomEffect");
   

3. Iterate through each ModelMeshPart in your model, and assign your Effect to the Effect property of the ModelMeshPart.

   C#

   public static void RemapModel(Model model, Effect effect)
   {
       foreach (ModelMesh mesh in model.Meshes)
       {
           foreach (ModelMeshPart part in mesh.MeshParts)
           {
               part.Effect = effect;
           }
       }
   }
   

4. Draw the Model, using the steps outlined in How To: Render a Model with one exception: instead of using BasicEffect, use the Effect attached to the model.

   C#

   foreach (ModelMesh mesh in terrain.Meshes)
   {
       foreach (Effect effect in mesh.Effects)
       {
           mesh.Draw();
       }
   }
