   [DX10] Constant buffer variable is always invalid
  Hello, whenever I use ID3D10Effect::GetVariableByName("CBModel")->AsConstantBuffer() the variable is invalid.This is the HLSL code:cbuffer CBModel{float4 texCoordScale[5]:packoffset(c0);float2 detColPowAndDetNormPow: packoffset(c5.x);};I've tried it with different .fx files but I can't get it to works :S
