Lightning Sample

I am attempting to use your effect in 3D. All I had to do was comment out the render target code and it works perfectly fine on PC. However, when I run it on the 360 it looks horrible, the lighting bolts have black squares and black sections. Here are the changes I made to the code:

public void GenerateTexture(GameTime gameTime, Matrix world, Matrix view, Matrix projection)
{
GraphicsDevice device = game.GraphicsDevice;

//device.SetRenderTarget(0, lightningRT);
//device.Clear(ClearOptions.Target,Color.TransparentBlack,1.0f,0);

lightningDrawEffect.Parameters["World"].SetValue(world);
lightningDrawEffect.Parameters["View"].SetValue(view);
lightningDrawEffect.Parameters["Projection"].SetValue(projection);
lightningDrawEffect.Parameters["StartColor"].SetValue(properties.InteriorColor.ToVector3());
lightningDrawEffect.Parameters["EndColor"].SetValue(properties.ExteriorColor.ToVector3());

device.RenderState.AlphaBlendEnable = true;
device.RenderState.BlendFunction = BlendFunction.Max;

using (VertexDeclaration vdecl = new VertexDeclaration(device, LightningVertex.VertexElements))
{
device.VertexDeclaration = vdecl;
device.RenderState.CullMode = CullMode.None;
lightningDrawEffect.Begin();
lightningDrawEffect.CurrentTechnique.Passes[0].Begin();
device.DrawUserIndexedPrimitives(PrimitiveType.TriangleList, lightningPoints, 0, lightningPoints.Length, indices, 0, indices.Length / 3);
lightningDrawEffect.CurrentTechnique.Passes[0].End();
lightningDrawEffect.End();
}

//device.SetRenderTarget(0, null);
//if(properties.IsGlowEnabled)
// postProcessGlow.ApplyEffect(lightningRT, lightningRT, properties.GlowIntensity);
}

protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.Black);

//draw it in 2D
Matrix viewMatrix = Matrix.CreateLookAt(new Vector3(0, 0, 10), new Vector3(0, 0, 0), new Vector3(0, 1, 0));
Matrix projectionMatrix = Matrix.CreateOrthographic(GraphicsDevice.Viewport.Width / 20, GraphicsDevice.Viewport.Height / 20, 0.01f, 50);
Matrix worldMatrix = Matrix.Identity;

//generate the lightning rendering
lightnings[currentItem].GenerateTexture(gameTime, worldMatrix, viewMatrix, projectionMatrix);

Rectangle rect = new Rectangle(0, 0, GraphicsDevice.Viewport.Width, GraphicsDevice.Viewport.Height);

//GraphicsDevice.Clear(Color.Black);
//spriteBatch.Begin(SpriteBlendMode.Additive);
//if (showBackground)
// spriteBatch.Draw(background,rect,Color.White);
////draw lightning texture over the scene
//spriteBatch.Draw(lightnings[currentItem].LightningTexture, rect, Color.White);
//spriteBatch.End();

base.Draw(gameTime);
}
