Hi,
now I've installed 3DGS after a half year again to explore the fascinating world of shaders with it and I must say it's veeery easy to assign them to models

But I've already two questions!

PostProcessing:
I've asked mk about PostProcessing to write fullscreen effects and he said that I need the Sylex3.0 plugin for this. Is it right or is there another way to implement them because you could write very cool effects with them!?

Level geometrie:
Now assigning shaders to entities is very easy but what's about assigning them to level geometrie? Can someone please give me a hint for this?

Greetings,
Asse.

basically you need to render the view (camera or additional extra view) into a texture using bmap_for_entity instruction. the used model in most cases is a screen aligned quad (screen entity) and this entity has the postprocess shader applied to it.

about level geometry and shaders: better forget it, its slow and in most cases not suitable...

That's a word man, didn't knew that rendering the screen to a texture within the engine is possible. Thanks.

Btw. I found the shadercollection and applied my own shader to level geometrie. When I find a way to display the framerate I'll see if it's too slow or not

Hehe, it works but is absolutely slow (I can count the fps per minute ). Maybe I toke the wrong commands? But I think this is no good solution since the manual says that bmap_for_screen is slow, too.

Code:

---

bmap_for_screen(bmap_for_entity(entScreen, 0), 1, 0);

---

oh, no, not like this. more like this:

Code:

---

material mat_vFx 
{
	effect="vFx1.fx";
}

entity rv_mdl 
{ 		
	type = <quad.mdl>;
	layer = 1;		
	view = camera; 
	x = 100;     
	y = 0;   
	z = 0;
	material=mat_vFx;
}

//use this funtion to enable/disable the postprocess:
function update_vFx(a) {
	if (a==1) 
	{
		rv_mdl.visible = 1;
		camera.bmap=bmap_for_entity(rv_mdl,0);
	}
	else
	{
		rv_mdl.visible = 0;
		camera.bmap=null;
	}
}

---

Hm, I think camera.bmap=bmap_for_entity(rv_mdl,0); only copies the entities skin to the camera, right? But how do I render to the entities skin?

no, this shows the camera content in the skin.

Sorry, but it doesn't work for me. Here's my code:

Code:

---

////////////////////////////////////////////////////////////////////////////////////

	my.pan      = 300;
	my.shadow   = on;
	
	while(!ent_Soldier)
	{
		wait(1);
	}
	
	while(me != null)
	{
		ent_animate(me, "stand", my.skill21, anm_cycle);
		my.skill21 %= 100;
		my.skill21 += 0.7 * time;
		wait(1);
	}
}

function func_ModelLoad()
{
	ent_Soldier = ent_create("soldier1.mdl", vector(0, 125, 0), func_Model);
	ent_Soldier.material = effect01;
}

function func_ModelRotation()
{
	while(mouse_right == 1)
	{
		mouse_pointer = 3;
		ent_Soldier.pan  += mouse_force.x * 2;
		ent_Soldier.tilt += mouse_force.y * 2;
		wait(1);
	}
	mouse_pointer = 2;
}


////////////////////////////////////////////////////////////////////////////////////

function main()
{
	video_set(1000, 675, 32, 2);
	video_window(nullvector, vector(1000, 675, 0), 0, "Shader Viewer");
	
	level_load(level_Scene);
	
	wait(3);
	
	mouse_mode = 1;
	
	camera.x = 0;
	camera.y = 0;
	camera.z = 0;
	
	camera.pan  = 90;
	camera.tilt = 0;
	camera.roll = 0;
	
	func_ModelLoad();
	
	while(!ent_Soldier)
	{

	}
	
	camera.bmap = bmap_for_entity(ent_Soldier, 0);

		mouse_pos.x = pointer.x;
		mouse_pos.y = pointer.y;

And a very simple effect:

Code:

---

//--------------------------------------------------------------//
// Constants
//--------------------------------------------------------------//
float4x4 matWorldViewProj;

//--------------------------------------------------------------//
// Vertex procesing
//--------------------------------------------------------------//
struct VS_INPUT
{
	float4 Position:	POSITION0;
	float2 TexCoords:	TEXCOORD0;
};

struct VS_OUTPUT
{
	float4 Position:	POSITION0;
	float2 TexCoords:	TEXCOORD0;
};

VS_OUTPUT vs_main(VS_INPUT Input)
{
	VS_OUTPUT Output;

	Output.Position		= mul(Input.Position, matWorldViewProj);
	Output.TexCoords	= Input.TexCoords;

	return Output;
}

//--------------------------------------------------------------//
// Pixel processing
//--------------------------------------------------------------//
texture entSkin1;

sampler Texture0 = sampler_state
{
	Texture		= <entSkin1>;
	AddressU	= clamp;
	AddressV	= clamp;
	MinFilter	= Linear;
	MagFilter	= Linear;
	MipFilter	= Linear;
};

float4 ps_main(float2 TexCoords: TEXCOORD0): COLOR0
{
	return tex2D(Texture0, TexCoords);
}

//--------------------------------------------------------------//
// Technique Section for Effect Group 1

{
	pass Pass_1
	{
		VertexShader	= compile vs_1_1 vs_main();
		PixelShader	= compile ps_1_1 ps_main();
	}
}

It's not a screen aligned quad but that shouldn't does matter. I just want to test it.

what happens ?? black model? i will create a small testlevel for you tonight and send it to you tomorrow, if you didnt got it working until then...

Neither black nor white, it is just rendered with it's skin

I'll try to get it working so you hasn't to do a night shift
