Hi, i have a doubt about my shader. I use it for bump mapping but there is something i think is wrong. I’d like to remove all the reflections in the shadow. You can see the picture, sorry if i’m not able to explain better.

The question is: i should change the normal map or there is something wrong in shader or in my code? I post the shader too:

Vertex:

```
uniform vec3 fvLightPosition;
varying vec2 Texcoord;
varying vec3 LightDirection;
attribute vec3 rm_Tangent;
void main( void )
{
gl_Position = ftransform();
Texcoord = gl_MultiTexCoord0.xy;
vec3 fvLightDirection = fvLightPosition;
vec3 fvNormal = normalize(gl_NormalMatrix * gl_Normal);
vec3 fvTangent = normalize(gl_NormalMatrix * rm_Tangent);
vec3 fvBinormal = cross(fvNormal, fvTangent);
LightDirection.x = dot( fvLightDirection.xyz, fvTangent );
LightDirection.y = dot( fvLightDirection.xyz, fvBinormal );
LightDirection.z = dot( fvLightDirection.xyz, fvNormal );
}
```

Fragment:

```
uniform vec4 fvDiffuse;
uniform vec4 fvAmbient;
uniform sampler2D baseMap;
uniform sampler2D bumpMap;
varying vec2 Texcoord;
varying vec3 LightDirection;
void main( void )
{
// fetch normal from normal map, expand to the [-1, 1] range, and normalize
vec3 lightVec = normalize(LightDirection);
vec3 normal = 2.0 * texture2D (bumpMap, Texcoord).rgb - 1.0;
normal = normalize (normal);
// compute diffuse lighting
float lamberFactor= max (dot (lightVec, normal), 0.0) ;
vec4 diffuseMaterial =texture2D (baseMap, Texcoord);
gl_FragColor = diffuseMaterial * fvDiffuse * lamberFactor ;
}
```
