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

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

C#

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

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

C#

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

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;
}
}
}

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();
}
}
