It seems a good way to go when the process has nothing to do with the render/panels colors and so.
MATERIAL *mtlEffect = mtl_create ();
mtlEffect.effect = "myeffect.fx";
PANEL *panSource = pan_create ( "", 1 );
...
panSource.bmap = bmap_createblack ( panSource.size_x, panSource.size_y, 32 );
set ( panSource, SHOW );
...
while ( 1 )
{
bmap_process ( panSource.bmap, NULL, mtlEffect );
wait(1);
}
Otherway I know two other similar ways to go. If you want to process just the panels, render them over a render target and show it throught an other panel with a bmap_process.
MATERIAL *mtlEffect = mtl_create ();
mtlEffect.effect = "myeffect.fx";
PANEL *panSource = pan_create ( "", 99 );
...
panSource.render_target = bmap_createblack ( panSource.size_x, panSource.size_y, 32 );
set ( panSource, SHOW );
PANEL *panDestiny = pan_create ( "", 1 );
panSource.bmap = bmap_createblack ( panSource.size_x, panSource.size_y, 32 );
set ( panDestiny, SHOW );
...
while ( 1 )
{
bmap_process ( panDestiny.bmap, panSource.render_target, mtlEffect );
wait(1);
}
If you want process the camera too, you can go like in the example above and include the camera render target in a material skin, or you can enlarge the render chain with a process_target view.
PANEL *panSource = pan_create ( "", 1 );
...
panSource.render_target = bmap_createblack ( panSource.size_x, panSource.size_y, 32 );
set ( panSource, SHOW );
MATERIAL *mtlEffect = mtl_create ();
mtlEffect.effect = "myeffect.fx";
mtlEffect.skin1 = panSource.render_target;
VIEW *camFinal = view_create ( 1 );
camFinal.material = mtlEffect;
set ( camFinal, SHOW | PROCESS_TARGET | CHILD );
camera.stage = camFinal;
In both cases, you'll need to check the texture sampler sources of the shader. hope it helps, salud!

Hi snake, I tried to replace "render_target" with "target_map", but it crashes each frame from the while loop: bmap_process ( panDestiny.bmap, panSource.target_map, mtlEffect );
I guess problem was that bmap for "panDestiny" wasn't defined...

ops, that is true  target_map! You can render all the panels in the same render target, but I remember some troubles with alpha... edit___ the source panel should have a content, too

In the same render target? You mean like this:
bmap_process(panel.bmap, panSource.target_map, mtlEffect);
I'm noob at rendering, shaders stuff, so please don't be confused  Edit: "content" ?

i mean use same bmap as render target in all the panels.
BMAP *bmpRT = bmap_createblack ( screen_size.x, screen_size.y, 32 );
PANEL *pan1 = pan_create ( "", 1 );
pan1.target_map = bmpRT;
PANEL *pan2 = pan_create ( "", 2 );
pan2.target_map = bmpRT;
PANEL *pan3 = pan_create ( "", 3 );
pan3.target_map = bmpRT;
while (1)
{
bmap_process ( panVisible, bmpRT, mtlEffect );
wait(1);
}
whit content i mean, a background bmap, or a digit, or so. Something to render in the render target. edit__ sorry, I miss with the hurry in the code above...
MATERIAL *mtlEffect = mtl_create ();
mtlEffect.effect = "pp_oldMovie.fx";
PANEL *panSource = pan_create ( "", 99 );
panSource.size_x = 128; // Define the size, otherwise...
panSource.size_y = 128; //
panSource.bmap = bmap_createblack ( panSource.size_x, panSource.size_y, 32 ); // ir has 0 values!!
panSource.target_map = bmap_createblack ( panSource.size_x, panSource.size_y, 32 );
set ( panSource, SHOW );
PANEL *panDestiny = pan_create ( "", 1 );
panDestiny.bmap = bmap_createblack ( panSource.size_x, panSource.size_y, 32 ); // panDestiny bmap was pan Source, my fault...
set ( panDestiny, SHOW );
while(1){
bmap_process(panDestiny.bmap, panSource.target_map, mtlEffect);
wait(1);
}

fucking shaders... I still can't get it... 
MATERIAL* mtlEffect = mtl_create ();
mtlEffect.effect = "pp_oldMovie.fx";
PANEL* panSource = pan_create("", 99 );
panSource.size_x = 128; // Define the size, otherwise...
panSource.size_y = 128; //
panSource.bmap = bmap_createblack(panSource.size_x, panSource.size_y, 32); // ir has 0 values!!
panSource.target_map = bmap_createblack(panSource.size_x, panSource.size_y, 32);
set(panSource, SHOW);
PANEL* panDestiny = pan_create("", 1);
panDestiny.bmap = bmap_createblack(panSource.size_x, panSource.size_y, 32); // panDestiny bmap was pan Source, my fault...
set(panDestiny, SHOW);
PANEL* test_pan = pan_create("bmap = inv_temp.bmp;", 1);
test_pan.target_map = panSource.bmap;
set(test_pan, SHOW);
while(1){
bmap_process(panDestiny.bmap, panSource.target_map, mtlEffect);
bmap_process(test_pan.bmap, panSource.target_map, mtlEffect);
wait(1);
}
I've defined size as you've said (can I use screen size, or isn't that necessary?), I've set target map of a new panel to the bmap of the main (source) panel, all I can see, is that my (test pan) panel is smaller than it was (playing with the size of the source panel doesn't affect on it), and it's isn't affected by shader! What am I doing wrong?

try this. it is tested
#include <acknex.h>
MATERIAL *mtlEffect =
{
effect = "
float4 vecCycle;
texture TargetMap;
sampler ColorSampler = sampler_state { Texture = <TargetMap>; };
float4 PS ( in float2 inTex: TEXCOORD0 ) : COLOR0
{
float2 Coord = inTex.xy * vecCycle.y;
float4 Color1 = tex2D ( ColorSampler, Coord );
Color1.a = 1.0f;
return Color1;
}
technique blur
{
pass p0
{
VertexShader = null;
PixelShader = compile ps_2_0 PS();
}
}
";
}
function main ()
{
video_set(256,256,32,2);
wait(1);
FONT *fntArial = font_create ( "Arial#30" );
STRING *strText = str_create ( "ABCDEFGHIJKL" );
PANEL *panSource = pan_create ( "", 1 );
panSource.size_x = 256;
panSource.size_y = 256;
pan_setstring ( panSource, 0, 0, 0, fntArial, strText );
pan_setstring ( panSource, 0, 0, 30, fntArial, strText );
pan_setstring ( panSource, 0, 0, 60, fntArial, strText );
pan_setstring ( panSource, 0, 0, 90, fntArial, strText );
set ( panSource, SHOW );
panSource.target_map = bmap_createblack ( 256, 256, 32 );
PANEL *panDestiny = pan_create ( "", 1 );
panDestiny.bmap = bmap_createblack ( 256, 256, 32 );
set ( panDestiny, SHOW );
while ( !key_esc )
{
bmap_process ( panDestiny.bmap, panSource.target_map, mtlEffect );
wait(1);
}
