Hey all (and ello if your listening),

I'm trying to get ello's simplegold shader to function. Sadly, the assembly looses me when I try to use the FX file (or even hardcode it for that matter) I get a string of errors about "uninitialized component(*)"... ok, I've gathered from looking at this that it may need an upgrade from DX8 to DX9 as I've heard there are differences in the ASM code.

Does anyone have a working DX9 version of this shader and or the equivilent shader in HLSL format (which I'd prefer so that I can play with settings and understand better what I'm looking at)? This is a nice simple shader with great impact and I'd love to be able to use it.

post the code.. it shouldnt be hard to convert to hlsl

Here is the code I downloaded off of ello's website:

Code:

---

 
//simple gold
// uses a grey randomnoise texture
//created by ello 2004
//visit www.earthcontrol.de
//its kinda easy to change the material color and shinyness

texture mtlSkin1;
matrix matWorldViewProj;
matrix matWorld;
vector vecViewDir;
vector vecViewPos;
vector vecSunDir;
technique secondset{
			pass p0 {
//				Cullmode=0;
				texture[0]=<mtlSkin1>;
				AlphaBlendEnable=1;
				BlendOp=1;
				VertexShaderConstant[0]=<matWorldViewProj>;
				VertexShaderConstant[4]=<matWorld>;
				VertexShaderConstant[12]=<vecViewPos>;
				VertexShaderConstant[13]=<vecSunDir>;
				VertexShaderConstant[14]=<vecViewDir>;
				VertexShaderConstant[20]={1,3,2,2};
				VertexShader=
				decl {
					stream 0;
					float v0[3];
					float v1[3];
					float v2[3];
				}	
				asm {
					vs.1.1
					m4x4 oPos,v0,c0
					
					m3x3 r0,v1,c4
					m4x4 oT1,r0,c14
					mul oD0,r0,c14
					mul r0,r0,c20
					mul oT0,v2,r0
					
				};

				PixelShaderConstant[0]={0.67,0.58,0.06,1.0}; //gold

				PixelShader=
				asm {
					ps.1.4
					texld r0,t0
					texcrd r1.xyz,t1.xyz
					dp3 r2,r1_bx2,r0  //use r0_bx2 for brighter reflex
					add r0,r0,r0
					add_sat r3,r0,r2
					lrp r0,r2,1-r3,r0
					add_x2 r0,r0_bias,v0	
					dp3 r0.b,r0,r0
					mul r0,r0,c0
				};
			}
			
		}

remove decl{} section and add this in asm {} section:
Code:

---

vs.1.1
dcl_position v0;
dcl_tangent  v1;
dcl_binormal v2;
m4x4 oPos, v0,c0;
.
.
.

May be You need to redefine constants {1,3,2,2} -> {1.0f,3.0f,2.0f,2.0f}
and add Fog calculations if You have it in your game.

Tried that already, but for what it's worth, here's the code snippit as it is now from the decl{}

Code:

---

 
				VertexShaderConstant[20]={1.0f,3.0f,2.0f,2.0f};
				VertexShader=
				decl {
						vs.1.1
						dcl_position v0;
						dcl_tangent  v1;
						dcl_binormal v2;
						m4x4 oPos, v0,c0;
					}
				asm {
					vs.1.1
					m4x4 oPos,v0,c0
					
					m3x3 r0,v1,c4
					m4x4 oT1,r0,c14
					mul oD0,r0,c14
					mul r0,r0,c20
					mul oT0,v2,r0
					
				};

Still receiving
"error X5326: Read of uninitialized component(*) in v0: *x/0 *y/1 *z/2 *w/3"

And this error repeats for at least 6 more lines with various registers until the error warning window runs out of room.

Like this:
Code:

---

 
				VertexShaderConstant[20]={1.0f,3.0f,2.0f,2.0f};
				VertexShader=
				asm {
					vs.1.1
					dcl_position v0;
					dcl_tangent  v1;
					dcl_binormal v2;
					m4x4 oPos, v0,c0;
					
					m3x3 r0,v1,c4
					m4x4 oT1,r0,c14
					mul oD0,r0,c14
					mul r0,r0,c20
					mul oT0,v2,r0
					
				};

-Rhuarc

Still might not work (though I could be wrong). We were trying to convert another one of his similiar shaders, and me nor him were able to get the DX9 version to work. Was quite strange

Perhaps...

I've made the sugested changes, but I'm still getting the same error (though not as many now) plus a new error about the lrp command.

Starting to think I may have to learn the ASM and convert it to HLSL unless someone here is ambisious enough to assist me with that?

i made some changes which i dont know why i had to do so, but its at least looking nearly like it should and get you into the right direction.
it hardly depends on a seamless uv_map for your model

Thanks, ELLO !
