Limited Rendering order with OpenGL objects with alpha channel?

OpenGL
1

Hello,

I have a little problem…

Im using a 2D textured Object with a Frame Texture and in the middle of the Texture there is a alpha area.

If I render the 2D textured Object at first, then the 2nd rendered OpenGL behind the frame is not visible behind the Alpha channel.
But if I render the 2D textured Object at last, then the 2nd rendered OpenGL behind the frame is visible.

Is there a way to eliminate this render order limit?

Thanks.

Ps.: I can not upload an Image with 620x280 14 Kb , why?

This is a common problem of order independent transparency. You should draw your objects in back to front order: more distant objects before closer objects. There are more advanced algorithms for this, but they all have their limitations.

Only objects with transparency should be drawn this way.
