The shader code I was using in this example is this one:

Code:

---

//  Basic Dot3 Bumpmapping.  
//
//  Calulates diffuse lighting from Sun and Level Light  
//
//  Needs:  A6.31 Comm+   DX9c  vertexshader.1.1 
//
//  Todo:  Lighting improvements
//
//  Eric Hendrickson-Lambert (Steempipe)
//
//  3/28/05:  Made changes for DX9 A6

---

So it may be a little out of date...

I tried another shader previously to this older one,
Code:

---

/**************************************************************/

// HLSL NormalMapping Shader

// -------------------------

// By:       Daniel "Rhuarc" Niezgocki

// Requires: []VS 1.1

//           []PS 1.4

// Skin1:    Texture

// Skin2:    Normal Map

//

// Usage:    Free to use, credit is nice, but not required.

/**************************************************************/

..but despite my Radeon Pro 9800 being PS 2.0 (I think thats correct ) I got a completely black model on my screen. Maybe you could help me out here, and point me in the right direction? Would be much appreciated.

Now that I have clarified the method it would be nice to put it into practise

i remember reading somewhere that Nvidia and ATI processors use normal maps differently, with one of the axises being inverted if u were to use a Nvidia-tested normal map on an ATI machine, and vice versa. i could be wrong.
and even if i AM right, it still shouldnt make ur model black. sorry, i can't help you.

EDIT: whoops! matt already pointed out the differences.

My experience when getting a black model, is that the shader does not work with the card, but is not...bad code, simply that it doesn't run on that card.

I say this as running shaders that work on my Radeon, on a Nvidia Mx400 recently produced the same results. I suspect that the bump code I used that is producing black is doing something that my card doesn't like, even if its a PS.2.0
