I'm relatively new to all of this, so I'm not sure what I'm doing wrong. Even some tutorials would be a major help =]
Here's a screenie of the problem.
Shader code
Code: Select all
float4x4 matViewProjection : ViewProjection;
sampler2D AlphaMap : register(s0) = sampler_state
{
ADDRESSU = WRAP;
ADDRESSV = WRAP;
ADDRESSW = WRAP;
};
sampler2D TextureOne : register(s1) = sampler_state
{
MipFilter = LINEAR;
MinFilter = LINEAR;
MagFilter = LINEAR;
ADDRESSU = WRAP;
ADDRESSV = WRAP;
ADDRESSW = WRAP;
};
sampler2D TextureTwo : register(s2) = sampler_state
{
MipFilter = LINEAR;
MinFilter = LINEAR;
MagFilter = LINEAR;
ADDRESSU = WRAP;
ADDRESSV = WRAP;
ADDRESSW = WRAP;
};
sampler2D TextureThree : register(s3) = sampler_state
{
MipFilter = LINEAR;
MinFilter = LINEAR;
MagFilter = LINEAR;
ADDRESSU = WRAP;
ADDRESSV = WRAP;
ADDRESSW = WRAP;
};

Output.Position = mul( Input.Position, matViewProjection );

return( Output );
}
PS_OUTPUT ps_main(in VS_OUTPUT input)
