Thanks for the help!

I haven't explicitly done anything to disable blending, but I do not have a blend state set for the technique to generate the G-buffer. Does this suffice, or is there something else I should do?

EDIT: I changed the technique to do this and the clear color doesn't affect the output anymore:

BlendState DisableBlending
{
BlendEnable[0] = FALSE;
RenderTargetWriteMask[0] = 1 | 2 | 4 | 8;
};
technique10 SSAO_T
{
pass P0
{
SetBlendState(DisableBlending, float4(0.0f, 0.0f, 0.0f, 0.0f), 0xFFFFFFFF);
}
}



About the normals, I was a bit confused as to what to do about that. I saw different code samples just writing the normals out, and some encoding it. I changed mine to do the encoding just now.

I've also changed the sampler to use point sampling. Does this automatically correct for the 0.5 offset, or do I need to do that myself?

I noticed a problem which I also fixed, and this seemed to have the most effect on the output. The textures I was rendering to were created with DXGI_FORMAT_R8G8B8A8_UNORM, and I changed that to DXGI_FORMAT_R16G16B16A16_FLOAT, as that is what is needed to hold the G-buffer.

This is my output right now, any idea where that height-map like effect is coming from?
