Hello Everybody,
Can anybody help me with programming a simple flat shader that takes color as input element. I am pretty new to v4 an computer graphics and have no background in programming.
Would it be something like adding this in the template shader?:
struct VS_IN
{
float4 AmbColor: COLOR;
};
struct vs2ps
{
float4 AmbColor: COLOR;
};
vs2ps VS(VS_IN input)
{
vs2ps output;
output.AmbColor = input.AmbColor
return output;
}
float4 PS(vs2ps In): SV_Target
{
???
}
Would appreciate the help,
Sven
If you want to use vertex colors then you need them in your mesh data and the shader below will work. It will let you know in the layout msg output pin if everything is right there. If you are just after having a user controlled color then check the dx11 constant shader, it already has this.
