Light on every model and not in the whole scene
- by alecnash
I am using a custom shader and try to pass the effect on my Models like that:
foreach (ModelMesh mesh in Model.Meshes)
{
foreach (ModelMeshPart part in mesh.MeshParts)
{
part.Effect = effect;
}
mesh.Draw();
}
My only issue is that every Model now has its own light source in it. Why is this happening and is this a problem of my shader?
Edit:
These are the parameters passed to the shader:
private void Get_lambertEffect()
{
if (_lambertEffect == null) _lambertEffect = Engine.LambertEffect;
//Lambert technique (LambertWithShadows, LambertWithShadows2x2PCF, LambertWithShadows3x3PCF)
_lambertEffect.CurrentTechnique = _lambertEffect.Techniques["LambertWithShadows3x3PCF"];
_lambertEffect.Parameters["texelSize"].SetValue(Engine.ShadowMap.TexelSize);
//ShadowMap parameters
_lambertEffect.Parameters["lightViewProjection"].SetValue(Engine.ShadowMap.LightViewProjectionMatrix);
_lambertEffect.Parameters["textureScaleBias"].SetValue(Engine.ShadowMap.TextureScaleBiasMatrix);
_lambertEffect.Parameters["depthBias"].SetValue(Engine.ShadowMap.DepthBias);
_lambertEffect.Parameters["shadowMap"].SetValue(Engine.ShadowMap.ShadowMapTexture);
//Camera view and projection parameters
_lambertEffect.Parameters["view"].SetValue(Engine._camera.ViewMatrix);
_lambertEffect.Parameters["projection"].SetValue(Engine._camera.ProjectionMatrix);
_lambertEffect.Parameters["world"].SetValue(
Matrix.CreateScale(Size) *
world
);
//Light and color
_lambertEffect.Parameters["lightDir"].SetValue(Engine._sourceLight.Direction);
_lambertEffect.Parameters["lightColor"].SetValue(Engine._sourceLight.Color);
_lambertEffect.Parameters["materialAmbient"].SetValue(Engine.Material.Ambient);
_lambertEffect.Parameters["materialDiffuse"].SetValue(Engine.Material.Diffuse);
_lambertEffect.Parameters["colorMap"].SetValue(ColorTexture.Create(Engine.GraphicsDevice, Color.Red));
}
