I have this line in my Vertex Shader: float4 Colors = tex2Dlod(ElevationSampler, float4(0, 0, 0.0f, 1.0f)); I'm expecting to see R:33,G:33,B:33,A:0, but instead I get 4 floats that are incredibly small (ie -2.14177722E+38). I've gone after the data in my Texture2D directly (in C#) to test: Texture.GetData<Color>(0, new Rectangle(0, 0, 10, 1), xx, 0, 10); Texture.GetData<float>(0, new Rectangle(0, 0, 10, 1), yy, 0, 10); When getting a "Color", I get exactly what I want. However, if I get a "float", the call returns what I see in the Vertext Shader. How can I get the Vertex Shader to give me the real RGB colors and not the exponential? I've got to be missing something simple. Thanks.
