The model is skinned and texture-coordinates are valid between 0 and 1. If i change in ps to

Code:

Color =  Color = float4(input.TexCoords.x,input.TexCoords.y,1,1);

i get a green/red ball. that means the texcoords are as they should be. but the tex2D returns always black.

without vertexshader it works as expected. but why? what i´m doing wrong?

Code:

#include <acknex.h>
#include <default.c>

ENTITY* eEarth;
MATERIAL* matEarth = {
	effect="Earth.fx";
}

...

void main() {
	level_load("");
	wait(2);
	
	
	eEarth = ent_create("Earth.mdl",vector(0,0,0),planet);
	eEarth.material = matEarth;
	
	
	vec_set(camera.x,vector(-7500,0,2500));
	
	camera.tilt=-20;
}

Code:

sampler2D smpScreen = sampler_state
{
	Texture = <TargetMap>;
	
	MinFilter	= linear;
	MagFilter	= linear;
	MipFilter	= linear;
	
	AddressU		= Wrap;
	AddressV		= Wrap;
};
 
 struct Out
 {
    float4 Position : POSITION;
     float4 Normal : TEXCOORD1;
     float2 TexCoords : TEXCOORD0;
 };
 
 Out vs (float4 pos : POSITION, float4 n : NORMAL, float2 tex : TEXCOORD0)
 {
 	Out output;
 	output.Position =mul(pos,matWorldViewProj);
 	output.TexCoords = tex;
 	output.Normal = n;
 	
 	return output;
 }

float4 ps(Out input) : COLOR
{
  	float4 Color;

  	Color =  tex2D(smpScreen,input.TexCoords);
  	
  	return Color;
}

{
	pass pass_00
	{
		VertexShader = compile vs_3_0 vs();
		PixelShader = compile ps_3_0 ps();
	}
}

You are looking for entSkin1 (see manual).

Oh, thank you very much. I saw Slins Shader Tutorial and he uses everytime TargetMap. But he also wrote Postprocessing-Shaders.

May i annoy with another issue? I solved, thanks to you, my problem with the object-shader, but now i try a postprocessing effect. i wrote this:

Code:

texture TargetMap;

sampler2D smpScreen = sampler_state
{
	Texture = <TargetMap>;
	
	MinFilter	= linear;
	MagFilter	= linear;
	MipFilter	= linear;
	
	AddressU		= Wrap;
	AddressV		= Wrap;
};

float4 Shader(float2 tex : TEXCOORD0) : COLOR
{
  	float4 Color=tex2D(smpScreen, tex);
  	return Color;
}



technique tech_00
{
	pass pass_00
	{
		VertexShader = null;
		PixelShader = compile ps_3_0 Shader();
	}
}

and added the effect with PP_Add (part of Slins PP_Helper.c)

Code:

MATERIAL* matBlur = {
	effect="blur.fx";
}

void main() {
...

PP_Add(matBlur,camera,NULL);
...
}

The result is that the TargetMap seems to remember the drawing of previous frames:

What is wrong (the planet and its moon moves around the sun; all of them have earth-skin yet)? I just want to have the rendered camera screen in this postprocessing shader. why it is not cleared after the last rendering?

ps: here is PP_Add, if you need it:

Code:

VIEW* PP_Add(MATERIAL* Material,VIEW* View,BMAP* bmap)
{
	//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(bmap != NULL)
	{
		PP_Temp_View.bmap = bmap;
	}
	
	//return the pointer to the new view
	return(PP_Temp_View);
}

Then the background won't be cleared and the result will be what is visible in your screenshot. Set it to COLOR_BLACK (1,1,1) instead.
