I'm having trouble with Matt Aufderheide' glow shader posted in the Wiki.

I'm not new to shaders, but I don't know why this one won't work. I saved it as a .fx file and included the usual material definition plus set a model to that material. However, I get:

Error in efect; glowmodel ID3DXEffectCompiler: There were no techniques


What could that be? Obivously it found the file, and the material definition points to it. I'm stumped.

You must have did something wrong, recheck that you copied everything. The fx worked for me.. but looked really strange.

This isnt my shader really, its been modified by someone else.. so i have no idea what the problem is.

huh what´s wrong with it? i really know it works... using it in many of my levels. as alexander esslinger said, check if you copied everything. if you don´t succeed, just post everything you got here.

Okay, here's what I've got.

In the .fx file, a copy and paste of the shader script:

Code:

                                   mov r0,t0

                        };
                }

                    pass p21 //this pass renders the model without the glow, so only the edgdes will glow..
                {
                        texture[0]=<entSkin2>;


                        zWriteEnable=true;
                        alphaBlendEnable=false;
                        zenable=true;

                                                      Texture[0]=<entSkin1>;

                                                      ColorArg1[0]=Texture;
                                                      ColorOp[0]=Modulate;
                                                      ColorArg2[0]=Diffuse;


                }
        }



//in your main script

//material glowmodel
//{
//        effect="glow.fx";
//}

//action anymodel{
//        my.material=glowmodel;
//        my.skill41 = float(0.3); // adjust the stength of the glow
//}


//  the glow model needs two skins, the first is the diffuse map, 
//  the second can be very small (e.g. 16x16) and must be very dark, almost black

Then in my main script:

Code:

---

material glowmodel
{
        effect="glow.fx";
}

function main()
{
	time_smooth = 0.666;
	randomize();
.....  

---

And in the entity function:

Code:

---

function player_fighter()
{
	player=my;
	my.alive=1;

	
	
//	my.bright = on;
	breakpoint();
	my.material = glowmodel;
	my.skill41 = float(0.6); // adjust the stength of the glow
...

What's wrong with that?

you put the "anymodel" action content into a function. dunno if this is the solution, but that´s the only thing that is different from what i use.

action playermodel {
my.material=glowmodel;
my.skill41 = float(0.3);
player_fighter();
}

something like this should work.

Shouldn't be. Let me check...


...No, it wasn't that.

Could someone zip up a working example for me?

sure. that´s my test level, you will need a ps/vs 2.0 graphics board for it. hope you don´t mind the stuff that´s in the level additionally, just have a look at the cone next to the furry lion. you can alter the stength of the glow by fiddling with the alpha channel.

it´s a *.cab, you need winRAR or filzip or equivalent.

ahem... did it work for you?

Thank you DaBroozar, that did work!

Comparing the files I found out what the problem was. This will be useful info for anyone out there with a foreign language version of Windows:

Make sure the text file is encoded as ASCII! (mine was encoded as UTF-8. This looks the same in your editor, but it will not compile)
