nope already thought of lights.... on or off no diffrence =)

Some things to check:

- The debug output from the debug version of the SDK to see if D3D is unhappy about anything. (The DirectX control panel applet).


- D3DRS_CULLMODE is set appropriately for your data.


- If you aren''t using a Z buffer, make sure D3DRS_ZENABLE to D3DZB_FALSE.


- If you are using a Z buffer, make sure:
a) the distance between your near and far clip planes isn''t too large.

b) the bitdepth of the z buffer is the same as the bitdepth of the frame buffer (a restriction on nVidia hardware).

c) your Clear() call has the D3DCLEAR_ZBUFFER flag set.


- The vertex (and index) buffers are being unlocked after being filled.


- Your TextureStageStates are handling the vertex colours correctly. For the vertex format you mention, you want stage 0 colour to do SELECTARG1 where ARG1 is DIFFUSE. For stage 0 alpha you want to do DISABLE, for stage 1 colour you want DISABLE.


- There is only one set of BeginScene()/EndScene() per frame.


- That you call SetVertexShader() with your vertex format.



A good thing to do to aid debugging of "I can''t see anything" problems is to set the colour you have in Clear() to something other than black so that if your triangles are being rendered, but in black you can see it.
