    <p>Hy everyone. I started re-coding my engine to convert it to directx 11. I'm now trying to get the basics working, but this error is really stoping me. I created a basic shader, a simple dot product of the normal and the view. I got it to compile without errors, but it dosnt works. It just totaly deforms the input mesh. I started debugging in vs2012, and found out that the pixel shader was getting as input all NaNs. I attached two screens and the shader code, if someone can provide any ideas, it would be really apriciated.</p> <p><a href="https://i.stack.imgur.com/5oFMI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5oFMI.png" alt="VS2012 Debugging info 1"></a> <a href="https://i.stack.imgur.com/GdfvU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/GdfvU.png" alt="VS2012 Debugging info 2"></a></p> <p>Vertex Shader</p> <pre><code>//---------------------------------------------------------------------------- // Constant Buffer Variables //---------------------------------------------------------------------------- cbuffer ConstantBuffer : register( b0 ) { matrix World; matrix View; matrix Projection; //float3 CameraPos; float Power; } //--------------------------------------------------------------------------- struct VS_INPUT { float4 Pos : POSITION; float3 Normal : NORMAL; }; struct VS_OUTPUT { float4 Pos : SV_POSITION; float3 Normal : TEXCOORD0; }; //-------------------------------------------------------------------------- // Vertex Shader //------------------------------------------------------------------------------- VS_OUTPUT VS( VS_INPUT input) { VS_OUTPUT output = (VS_OUTPUT)0; output.Pos = mul( input.Pos, World ); output.Pos = mul( output.Pos, View ); output.Pos = mul( output.Pos, Projection ); output.Normal = mul( float4( input.Normal, 1 ), World ).xyz; //output.wNormal = input.Normal; return output; } </code></pre> <p>And here the Pixel Shader</p> <pre><code>//------------------------------------------------------------------------------ // Constant Buffer Variables //------------------------------------------------------------------------------ cbuffer ConstantBuffer : register( b0 ) { matrix World; matrix View; matrix Projection; float Power; } //------------------------------------------------------------------------------ struct VS_OUTPUT { float4 Pos : SV_POSITION; float3 wNormal : TEXCOORD0; }; //----------------------------------------------------------------------------- // Pixel Shader //----------------------------------------------------------------------------- float4 PS( VS_OUTPUT input) : SV_Target { //return pow(dot(input.wNormal,float3(0,0,0)),Power); // fixed camera, just for now return float4(0.1,0.6,0.1,1); } </code></pre> <p>And at last, i created a xml file structure for my shaders, that i then parse, dont know if it relevant, but</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;vs path = "D:\\Documentos\\Visual Studio 2012\\Projects\\Fusion Engine\\Tests\\ConstantLighting_VS.hlsl" name ="VS" target = "vs_4_0"&gt; &lt;/vs&gt; &lt;ps path = "D:\\Documentos\\Visual Studio 2012\\Projects\\Fusion Engine\\Tests\\ConstantLighting_PS.hlsl" name ="PS" target = "ps_4_0"&gt; &lt;val1 type = "scalar" value = "0.456645" name = "Power"/&gt; &lt;/ps&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
