I am using MeshNormalEffect.cs and am able to break on ApplyMaterial, however when I implement the interface GetRequiredRenderingPassesCount is never called.

Code:

public class MeshNormalColorEffect : Ab3d.DirectX.Effect, Ab3d.DirectX.IMultiPassEffect
{
...
        public int GetRequiredRenderingPassesCount(IList<ILight> lights, RenderingContext renderingContext)
        {
            throw new NotImplementedException();
        }

        public virtual void ApplyRenderingPass(int renderingPassIndex, RenderingContext renderingContext)
        {
            throw new NotImplementedException();
        }
}

Is there something else I need to call in order to enable passes?
