HLSL - vs with fixed pipe texture problem
Author
Hello again ;-)
Im trying to force my app to run on some old hardware without ps. All i need is to use my vertex shader and render model with texture.
I create effect file with only vertex shader - all works ok.
struct VS_OUTPUT
{
float4 Pos : POSITION;
float2 Tex0 : TEXCOORD0;
};
VS_OUTPUT VShade(VS_INPUT In)
{
VS_OUTPUT Out = (VS_OUTPUT) 0;
Out.Pos = In.Pos;
Out.Tex0 = In.Tex0;
return Out;
}
And i get black model. Texture is set this way:
effect->SetTexture("Texture1",tex);
What could go wrong? Should i set some render extra states to make fixed pipe texture my models? I tried
ColorArg0[0] = DIFFUSE;
but with no effect... any ideas?

Hello Armadon!
Thanks but i dont want to use ps - i want to use vs with fixed pipeline. I want this to run on hardware that doesnt support ps at all - only vs_1_1.. any other ideas?

Thanks vNistelrooy, but that was not the case.. i was able to figure out whats wrong - when i set texture in the effect i cant specify stage, like i do when setting it with device (lpD3DDevice->SetTexture(0,tex) )
Texture set with effect has random stage - how can i avoid this? Is there a method of forcing effect file to load specific texture to specific stage?
[edit]
Nope, i was wrong - still doesnt work. It was rendered textured because there was pixel shader loaded from previous model.
No one ever tried to use vertexshader without ixel shader and render a textured model?

In your effect file set pixel shader to null, forcing usage of fixed pipeline:
Also, when you set texture with effect interface (using whatever name, like "Texture1"), you got to have a texture variable withing the effect with that name. Then you can use it with pixel shader.
To use fixed pipeline, use standard pDevice->SetTexture(stage, pTex);
Well, I'm relatively new to shaders, so hope I'm right ;)

You are right, but it still doesnt work. I set texture usig device way, i set ps to null, and i get black model.
