You actually have to create an extra view for each pp effect which have to be chained together using the stage member.
This helper functions written by Slin make it more comfortable:

Code:

/////////////slindev.wordpress.com////////////////
//////////////////////////////////////////////////


//temporary pointers
VIEW* PP_Temp_View;


//Add an effect to a views stage chain
VIEW* PP_Add(MATERIAL* Material,VIEW* View,BMAP* btarget0,BMAP* btarget1,BMAP* btarget2,BMAP* btarget3)
{
	//find the last view of "View"s effectchain and store its pointer
	PP_Temp_View = View;
	while(PP_Temp_View.stage != NULL)
	{
		PP_Temp_View = PP_Temp_View.stage;
	}
	
	//create a new view as the stored views stage
	PP_Temp_View.stage = view_create(0);
	set(PP_Temp_View.stage,PROCESS_TARGET);
	
	//assign "Material" to the just created view
	PP_Temp_View = PP_Temp_View.stage;
	PP_Temp_View.material = Material;
	
	//if a bmap is given, render the view into it
	if(btarget0 != NULL){	PP_Temp_View.bmap    = btarget0; }
	if(btarget1 != NULL){	PP_Temp_View.target1 = btarget1; }
	if(btarget2 != NULL){	PP_Temp_View.target2 = btarget2; }
	if(btarget3 != NULL){	PP_Temp_View.target3 = btarget3; }
	
	//return the pointer to the new view
	return(PP_Temp_View);
}

//remove an effect from a views stage chain
int PP_Remove(MATERIAL* Material,VIEW* View,VIEW* StageView)
{
	//find the view with the material selected or "StageView" and the previous view && ((StageView == NULL)+(PP_Temp_View.stage != NULL)) != 0
	PP_Temp_View = View;
	while(PP_Temp_View.material != Material)
	{
		View = PP_Temp_View;
		PP_Temp_View = PP_Temp_View.stage;
		
		//return one if the stage doesn�t exist
		if(PP_Temp_View == NULL){return(1);}
	}
	
	//pass the views stage to the previous view
	View.stage = PP_Temp_View.stage;
	
	//pass the render target
	View.bmap = PP_Temp_View.bmap;
	View.target1 = PP_Temp_View.target1;
	View.target2 = PP_Temp_View.target2;
	View.target3 = PP_Temp_View.target3;
	
	//reset the views bmap to null
	PP_Temp_View.bmap    = NULL;
	PP_Temp_View.target1 = NULL;
	PP_Temp_View.target2 = NULL;
	PP_Temp_View.target3 = NULL;
	
	//remove the view
	ptr_remove(PP_Temp_View);
	PP_Temp_View=NULL;
	
	//return null if everything worked
	return(0);
}


//remove all postprocessing from the view
void PP_Remove_All(VIEW* View)
{
	if(View.stage == NULL){return;}
	PP_Temp_View = View.stage;
	View.stage = NULL;
	View.bmap = NULL;
	while(PP_Temp_View.stage != NULL)
	{
		View = PP_Temp_View;
		PP_Temp_View = View.stage;
		
		//pass the views stage to the previous view
		View.stage = NULL;
		
		//reset the views bmap to null
		View.bmap = NULL;
		
		//remove the view
		ptr_remove(View);
	}
}

Then you can do something like:

Code:

...
camera->bmap=ColorTarget01_bmap;

vertical_blur_mtl->skin1=ColorTarget01_bmap;
PP_Add(vertical_blur_mtl,camera,ColorTarget02_bmap,NULL,NULL,NULL);

PP_Add(horizontal_blur_mtl,camera,NULL,NULL,NULL,NULL);//render to backbuffer
...

Tanks Hummel , its work. but i have a problem.whene i use PP_ADD , and set mtl_hdr PPShader , my view size (x,y in game) is changed to small and i cant change it. i set video to "1280,720,32,0" but in the game window , my viewport is "320,240". please help me. tanks.

}

when i dont use "mtl_hdr" , its work normally.

Perhaps you only need to deactivate the AA, just try it.
