and what did you expect from that shader?
when i apply it to a model the color changes as the camera-angle changes

btw, both of you forgot the bracket at the beginning of the vertexshader asm section

so lets look:

Code:

---

 
	technique test
	{
		pass P0
		{
			VertexShaderConstant[0]=<matWorldViewProj>;
			VertexShaderConstant[4]=<matWorld>;
			VertexShaderConstant[10]= <vecLight>;
			VertexShaderConstant[15]= <vecViewDir>;
									
			Texture[0] = <entSkin1>;
			Texture[1] = <entSkin2>;
			
			VertexShader = asm 
			{
				vs_1_1
				
                                dcl_position v0
			        dcl_normal v3
				dcl_texcoord0 v7                             

				def c16, 0, 175, 175, 100  
				def c20, 175, 0.011,0,0  
				
				m4x4 oPos, v0,c0
				
				sub r0, v3, -c15   //r0 now contains : normal - ( - vecViewDir)

				mul r0, r0, c16  //r0 gets multiplied by cyan
				
				mul oD0, r0, c20.y  //ro gets scaled down by 0.011 			
			};
			
		}
	}
