I tried adding it, but it gives an error and defaults to vertex lighting material. Then I added "float3 Sun : TEXCOORD6;" and theres no error, but it doesn't show the first light properly(and still no sun). I've also tried messing in the PS part and edited out light1 and put in Sun instead, but no luck. Am I messing things up?

I added some stuff, I'm gonna go "debug" it...

I'll post my results soon...

Will be looking forward to it. Thanks for your help.

Hi

Its not working for me, it looks like the model is not change by the shader

What I'm doing wrong?

1) Put the shader in a fx file
2) wrote a wdl with the following statement:

material mat_nm3lights
{
effect = "nm3light.fx";
}

3) attached material in WED to model

did you include a light near the model (dynamic light that is)

add in effect_load() in a starter function


Code:

---

string fxNM3Light = "nm3light.fx";

material mat_nm3lights
{
    effect = fxNM3Light;
}

starter loadFX
{
    effect_load(mat_nm3lights, fxNM3Light);
}

just thought I'd let you know I'm still workin on this. I accidently coppied it onto my work drive instead of my thumbdrive, so I havn't been able to work on it this weekend.

So far I [theoretically] have 5 lights in one pass. It should work, but needs to be tested. I did this by copying the light AttenuationX into the LightX:TEXCOORDX.

I'll be at work tomorrow, and post my results...

Np, I'm looking forward to testing it.

BTW - why 5 lights in one pass? Is this needed to allow sunlight?

starter is no longer used as a function, to use a starter function use this:

Code:

---

function LoadFX_startup()
{
     effect_load(mat_nm3lights, fxNM3Light);
}

@bstudio: Thanks, I had heard of this update, but never got around to actually using it. I'll remember that...


@William: It's not required, it's just an optimization. Using less passes, yet still getting the same effect = better speeds... correct? I currently only have 5 lights, but it still has room for more in its pass... (1 or 2 texcoords left)
