hlsl texture Sample result?

18 May 2012 - 10:14 PM

i have a texture with a DXGI_FORMAT_A8_UNORM format. in hlsl:

float4 color = tex.Sample(sample_state, Texcoord.xy);

then i got the color with a correct alpha channel result and the each r/g/b channel result of 0.

is there any way to get other specified rgb result, when the texture's DXGI_FORMAT has no rgb channel component? thx
