Okay, here's my problem...
I've made a simple shader for blur

Code:

---

float4 vecSkill1;
texture entSkin1;

sampler basemap = sampler_state
{
   Texture = <entSkin1>;
   MinFilter = Linear;
   MagFilter = Linear;
   MipFilter = Linear;   
   AddressU  = clamp;
   AddressV  = clamp;
};

float4 mainPS(float2 Tex: TEXCOORD0) : COLOR 
{  
  float2 Color1 =  {Tex.x+vecSkill1.x,Tex.y-vecSkill1.x};
  float2 Color2 =  {Tex.x-vecSkill1.x,Tex.y+vecSkill1.x};
 
  float4 Color = tex2D( basemap, Tex.xy);
  Color += tex2D( basemap, Color1);
  Color += tex2D( basemap, Color2);
  Color += tex2D( basemap, Tex.xy+vecSkill1.x);
  Color += tex2D( basemap, Tex.xy-vecSkill1.x);
  return Color/5; 
}

technique blur
{
	pass Object
	{
		PixelShader = compile ps_1_4 mainPS();
	}
}

works fine

now i created a view entity (1024x768 bmp sprite) and a view for post-processing

Code:

---

ENTITY* screen_grab = 
{
	type = "screen.bmp";
	layer = 1;
	view = camera;
	x = 1000;
	flags2 = VISIBLE;
}

VIEW* PP =
{
	flags = VISIBLE;
	layer = -1;
}

---

now i render my view to entity

Code:

---

	PP.bmap = bmap_for_entity(screen_grab,0);
	while(1)
	{
		vec_set(PP.x,camera.x);
		vec_set(PP.pan,camera.pan);
		wait(1);
	}

---

works fine

but when i apply blur material to the entity there's no blur, and the rendered texture is messed up like this


i'm a noob at shaders, perhaps more experienced users can help me?

nevermind, i've fixed it by reducing texture size to 512
