Hi

Is this coming out soon, I've tried 2 shaders from the forum and all I get is a black (very dark) model.

In this day and age it should be already a basic thing and specially for people like me who can't work out what I'm doing wrong

Agree...a normal map template would be an excellent and very useful tool

Well, you don't need to wait for the templates, normalmapping is simple:

Code:

---

MATERIAL mtl_bump
{
//Normal Map must be on Skin2
	effect=
	"
	#include <transform>
	#include <fog>
	#include <pos>
	#include <normal>
	#include <tangent>

	float4 vecSunDir;
	float4 vecColor;	

	texture entSkin1;	// texture
	texture entSkin2;	// normal map

	sampler sBaseTex = sampler_state { Texture = <entSkin1>; };
	sampler sBump = sampler_state { Texture = <entSkin2>; };

	struct out_bump
	{
    	float4 Pos:     POSITION;
    	float  Fog:		FOG;
    	float4 Color:	COLOR;
    	float2 Tex:   	TEXCOORD0;
    	float2 Bump:   	TEXCOORD1;
    	float3 Normal:	TEXCOORD2;
    	float3 Light:	TEXCOORD3;
	};

	out_bump vs_bump(
		in float4 inPos: 	POSITION, 
		in float3 inNormal:	NORMAL,
 		in float2 inTex: 	TEXCOORD0,
 		in float3 inTangent: TEXCOORD2)
	{
   		out_bump Out;

		Out.Pos	= DoTransform(inPos);
		Out.Tex	= inTex;
		Out.Bump = inTex;	// different coordinates required for ps_1_1
        Out.Color = float4(1.0,1.0,1.0,1.0);
		Out.Fog	= DoFog(inPos);
		
		CreateTangents(inNormal,inTangent);
		float3 N = matTangent[2];
		
// transform the output values into the 0..1 range
		Out.Light = DoTangent(-vecSunDir) * 0.5 + 0.5;
		Out.Normal = DoTangent(N) * 0.5 + 0.5;

		return Out;		
	}


    float4 ps_bump(out_bump In): COLOR
	{
		float4 base = tex2D(sBaseTex,In.Tex);
		float3 bumpNormal = tex2D(sBump,In.Bump);
		float diffuse = saturate(dot(In.Light*2 - 1,bumpNormal*2 - 1));
#ifdef SHADOW		
		diffuse *= saturate(4 * dot(In.Light*2 - 1,In.Normal*2 - 1));
#endif		
		return base * diffuse;
	}

	technique bump
	{
		pass One
		{		
			VertexShader = compile vs_1_1 vs_bump();
			PixelShader = compile ps_1_1 ps_bump();
		}
	}

	";
}

You need 6.50, the template6 file "default.fx" must be in the path, and the model must have a normal map on its second skin. You can also save the effect to an .fx file and assign it to the model directly in MED.

Fantastic! Thanks for this.

Anyone know how to make this work with dynamic lights? Also, how would this blend the shadow map in with the effect?

Hi JCL

Easy for a guy like you

Thanks for the code will play with it, so you must use templates!

whats hard about it? you store it in an fx file, make a material with effect="file.fx"; and make your second skin in the model a normal map

I was talking about the shader code

How to make an fx files?

Rightclick, new, Text. Then rename new document.txt to normalmapping.fx, open it with the standart editor and copy&past the shader code.

Okay, shader code done. It called mt_material1.fx
Then I try this:
I put two skins in the same (static model)(from Med), one is the normal map (obteined with Gimp from the first skin) .
Then I include the nm.fx in the try.wdl , include material.wdl in the project and assign the mt_material1 at the model.
It appairs the same (?), perhaps the two skins should named "entskin"? I should miss some passages here.
