Problems with font in XNA

Question

I'm trying to make some games in XNA, but I have the following problem:

When I load and show the 3d model on the screen, there is everything ok. You can see it on this picture:
Img1

But when I add a font to my program

C#

font1 = Content.Load<SpriteFont>("Fonts/Fon1");

and show some text

C#

spriteBatch.Begin();
spriteBatch.DrawString(font1, "Speed: ", new Vector2(5, 5), Color.Red);
spriteBatch.End();

I suddenly get that result

Why is my model in the second image transparent?
Is there any property that somehow makes models transparent when displaying 2D sprites?

Please help.

Hi, I think it's a Blend problem but I don't have enough informations :

do you draw the string before or after the 3d model ?
can you add the code for drawing of the 3d model ?

I draw the string after drawing model, but if I reverse that, there's no change.
My model drawing code is from that page:

, but it has some small modifications.

Ok, I tried to find why you got that, take a look at this post : http://stackoverflow.com/a/4180552

It's seems to be the same problem, a render state problem after drawing with spritebatch

Change this attribute after using spritebatch

GraphicsDevice.RenderState.DepthBufferEnable = true;

I could not find the RenderState property inside GraphicsDevice, but I found this:

C#

GraphicsDevice.BlendState = BlendState.Opaque;
GraphicsDevice.DepthStencilState = DepthStencilState.Default;

on that site: http://blogs.msdn.com/b/shawnhar/archive/2010/06/18/spritebatch-and-renderstates-in-xna-game-studio-4-0.aspx[^]

Thanks you very much for your help!

Ok, I see this property is not implemented in XNA 4.0
