before VS all vertexes have different position

Problem with compile shader from file
Author
I find only one problem:
before VS all vertexes have different position
and after VS all 0...so how to fix it?

see that column VTX in PostVS tab? 0 1 2 3...click one of those and debug your vertex shader. IDX are indices, looking that picture, they are not correct either. Am guessing, the homogeneous matrix is not being update in the shader. Debug and find it out

if i understand correctly this is 0 vertex debug.
and Registry:
c4 (1.000,0.000,0.000,0.000) float4
v0 (909.163,59.139,-1585.124,1.000) float4and what is wrong? I can post my VS too.
As far as I remember c# are constant registers and v# are output registers but don't remember much though. Debug your shader in via HLSL rather than going through the disassembled code...anyways, when debugging your shader monitor the value of variables from the variables tab. Look at the value of homogeneous matrix from that tab.

well i asked there and sb tell me that i can multiply anything by a zero matrix and tend to get null vectors.
...
its my shader code...where can i multiply by a zero here?
...
float4x4 worldViewProj;
struct VS_INPUT
{
float3 position : POSITION;
float4 color0 : COLOR0;
float2 texcoord0 : TEXCOORD0;
};
struct VS_OUTPUT
{
float4 hposition : POSITION;
float4 color0 : COLOR0;
float2 texcoord0 : TEXCOORD0;
};
VS_OUTPUT main( VS_INPUT IN )
{
VS_OUTPUT OUT;
float4 v = float4( IN.position.x,
IN.position.y,
IN.position.z,
1.0f );
OUT.hposition = mul( v, worldViewProj );
OUT.color0 = IN.color0;
OUT.texcoord0 = IN.texcoord0;
return OUT;
}
its my shader code...where can i multiply by a zero here?
well, use PIX to check the value of [color=#000000][size=2]
worldViewProj
in your shader. Am sure that matrix is not being updated in the shader from external source

well, use PIX to check the value of
i tried maybe all...rad SDK and i don't know how to chek it
, can you plz tell me where i can see it?P.S. If you sure where is the problem - can you simply say how to fix it?
