Hi all,

How to change light settings (ambient, diffuse, emissive) of material defending on alpha channel or different skin using effect ? Please help ?

I want alpha channel or different skin to mark positions where i have to change light settings.

you can integrate something like this into your shader assuming that white parts in the alphachannel is the part you want to have blinking
...
float4 tex = tex2D(yoursampler,texCoord.xy);
float4 blueblink = vecSkill41.x*float4(0,0,1,1)*tex.a;

then you need to add the blueblink to your coloroutput

...
return tex+blueblink;
}

thus you can modify the blinker thru c-script by setting the models skill41=float(your value);

hope this is of any help for you

Thanks for your advice. But i dont have any skill with shader, therefore it is very difficult for me. Can you give me some code example ?

Without vertex and pixel shader is it possible ?

If I were you, and you just want a quick change in color (not a slow change over time), just make another skin instead of using the entity.light or materials. You can just change the yellow to brown with the free GIMP (www.gimp.org) program with the selecting by color button, then you can change that selections color (either with a hue change or by just painting it directly). Then you can keep the same color for those little logos on the car. To change the skin of the car, just put my.skin=2 in your script. Thanks!

Thanks WING,

I know that i can make different skins and i can manipulate them. But i dont want new skin, because :
- It will take RAM, HDD, CD space (My level already 360MB)
- I also want that player can choose their car color from any color.

Ok, another thing you could do is make it two different models that always stay in the same position but delete the faces of the parts that aren't part of the logo (the main body) and then have the other model just be the the main body (so you separated the original model into two, one with the parts that do change color and one where they don't). Then always keep the models at the same position and just change the color of the car body so you can keep the logo the same color.
