I'm having problems creating the Input Layout for a shader I'm using.
The CreateInputLayout() returns me invalid arg, but I have checked the parameters several times and I don't see anything wrong ( I know it has to be something wrong some where )
This is the code snip where I create the Input Layout
m_pSectionVertexLayout = NULL;
hr = TheGraphics.GetGraphicsDevice()->CreateInputLayout( D3DVERTEX_Layout, D3DVERTEX_DECL_SIZE,
m_pTerrainVertexShader->GetShaderBuffer()->GetBufferPointer(),
m_pTerrainVertexShader->GetShaderBuffer()->GetBufferSize(),
&m_pSectionVertexLayout ) ;
if (FAILED(hr))
{
log_graphics_critical(" CTerrainSection::LoadTerrainSection - Error creating the section Input Layout");
return hr;
}
Here is the vertex declaration
typedef struct SVertex
{
D3DXVECTOR3 v; // Actual Vertex
D3DXVECTOR3 n; // Normal Vector
D3DXVECTOR2 tu1; // Texture Coordinates
D3DXVECTOR2 tu2; // Texture Coordinates
D3DXVECTOR3 t; // tangent Vertex
D3DXVECTOR3 bn; // BiNormal Vector
} D3DVERTEX;
#define D3DVERTEX_DECL_SIZE 6
// Define the input layout
const D3D10_INPUT_ELEMENT_DESC D3DVERTEX_Layout[] =
{
{ "SV_Position", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "Normal", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 12, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "TEXCOORD0", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 24, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "TEXCOORD1", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 32, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "TANGENT", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 40, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "BINORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 52, D3D10_INPUT_PER_VERTEX_DATA, 0 },
};
I have checked the creation/compilation of the shaders and it is fine, it doesn't gives me any errors.
Here is the shader if you want to look at it, this is just a small shader which I later want to convert to a bump mapping shader, so, the only thing that it does at this time ( or at least it supposed to do ) its translate the vertices from one space to world space.
//-----------------------------------------------------------------------------
// Global variables
//-----------------------------------------------------------------------------
cbuffer cb0
{
row_major float4x4 mWorldViewProj : packoffset(c0); // World * View * Projection transformation
float fTime : packoffset(c5.y); // Time parameter. This keeps increasing
// Notice, that this parameter is placed in c5.y.
// If it were packed by the default packing rules,
// it would be placed in c4.x
};
//-----------------------------------------------------------------------------
// Vertex shader input structure
// { "SV_POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
// { "NORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 12, D3D10_INPUT_PER_VERTEX_DATA, 0 },
// { "TEXCOORD0", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 24, D3D10_INPUT_PER_VERTEX_DATA, 0 },
// { "TEXCOORD1", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 32, D3D10_INPUT_PER_VERTEX_DATA, 0 },
// { "TANGENT", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 40, D3D10_INPUT_PER_VERTEX_DATA, 0 },
// { "BINORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 52, D3D10_INPUT_PER_VERTEX_DATA, 0 },
//-----------------------------------------------------------------------------
struct VS_INPUT
{
float4 Position : SV_Position; // Vertex Position
float3 Normal : Normal;
float2 TexCoord0 : Texcoord0;
float2 TexCoord1 : Texcoord0;
float3 Tangent : Tangent;
float3 Binormal : Binormal0;
};
struct VS_OUTPUT
{
float4 Position : SV_Position; // vertex position
};
VS_OUTPUT VSBump( in VS_INPUT pVertex )
{
VS_OUTPUT Output;
// Change the y of the vertex position based on a function of time
// and transform the vertex into projection space.
Output.Position = mul( pVertex.Position, mWorldViewProj );
return Output;
}
Any hint/clue/advice in how I can fix this or where did I make the mistake will be highly appreciated.
Thanks in advance

Solved - Here is the answer for case documenation...
/********************************************************/
I have used a bad index on the vertex declaration the new vertex declaration its now like this
{ "SV_Position", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "Normal", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 12, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "TEXCOORD", 0, DXGI_FORMAT_R32G32_FLOAT, 0, 24, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "TEXCOORD", 1, DXGI_FORMAT_R32G32_FLOAT, 0, 32, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "TANGENT", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 40, D3D10_INPUT_PER_VERTEX_DATA, 0 },
{ "BINORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 52, D3D10_INPUT_PER_VERTEX_DATA, 0 },
Thanks to Zeux for the help :D
