[D3D] Mixing 2d and 3d

[chronozphere]

Hi all

I already know 2 ways of drawing 2d using D3D:
Those are:

** Using Transformed Vertices.
** Using The Orthographic Perspecitve

These are mentioned in this thread.
Now i want my engine to be able to mix up 2d and 3d in the same scene.

For 2d i can used Transformed vertices and for the 3d Untransformed and Unlit vertices.
So i need a way to use different vertex types in one render- sequence.

I tried calling SetPixelShader but it seems to raise an AV in D3D8.DLL when its called between beginscene and endscene.

Can someone explain me how to Mix 2d with 3d in the same scene, how do you guys do this

Thanx in advance.
