Hello All.
I have some problem with my shader. I have function which sets variables in my pixel shader. It works fine for all my shaders, but not for this
Now my setter function
and always GetConstantByName(NULL, "xBillboardTexture") returns me NULL.
I can't understand where is problem.

float4x4 xWorld;
float3 xCamPos;
float3 xAllowedRotDir;
Texture xBillboardTexture : TEXTURE0;
sampler textureSamplerTree = sampler_state

BBPixelToFrame BillboardPS(BBVertexToPixel PSIn)

/*Vertex shader not important*/

float4 inPosTmp = float4(inPos, 1);
float4 center = mul(inPosTmp, xWorld);
float3 eyeVector = center.xyz - xCamPos;
float3 upVector = xAllowedRotDir;
upVector = normalize(upVector);
float3 sideVector = cross(eyeVector,upVector);
sideVector = normalize(sideVector);
float3 finalPosition = center.xyz;

float4x4 preViewProjection = mul (xView, xProjection);
Output.Position = mul(finalPosition4, preViewProjection);
Output.TexCoord = inTexCoord;
return Output;
}Now my setter function
HRESULT Shader::SetTexture(IDirect3DTexture9 * baseTexture, char * var_name)
{
D3DXHANDLE handle;
handle = pdxVertexConstants->GetConstantByName(NULL, var_name);
if (localDevice && pdxPixelConstants && (handle = pdxPixelConstants->GetConstantByName(NULL, var_name)))
{
DWORD shaderSamplerIndex = pdxPixelConstants->GetSamplerIndex(handle);
localDevice->SetTexture(shaderSamplerIndex, baseTexture);
return S_OK;
}
return E_FAIL;
}and always GetConstantByName(NULL, "xBillboardTexture") returns me NULL.
I can't understand where is problem.
