Hi everyone,

Hoping this is an easy question... I'm trying to draw a 2D parallax background (eg. Dark Invaders bg) with 3D rendered objects on top.

Using dbSprite(), I see the background fine but the 3D objects are hidden.

If I specify dbDrawToBack() or dbDrawSpritesFirst(), I only see my 3D renders and the blue background of the 3D camera, without the sprite background at all!

What am I doing wrong?

Thanks for your help!

Maybe you could create a 3d game and make it look 2d by placing an object plane that covers the entire height and width of the screen, I don't know, just a thought.

Kklouzal, thanks for the suggestion. Yeah, thought about that also, but would be with less complications and more exacting for my purposes if I could just post multiple background layers with transparencies directly to screen coordinates. Seems like it would be a fairly simple thing to achieve, I know XNA can do exactly that... 2D background with 3D on top... I must just be doing something wrong.

Any more ideas out there?

Disable the blue camera background by dbBackdropOff() command.

Whenever I call dbBackdropOff() it seems to make no apparent change. My sprite(s) do not show aswell..
