is there an easy understandable shader that makes an object shine like metal, the kinda shine that is used with the easy water code and stuff but then without the waves i hope i made myself clear and someone can help me thank you.

Cubic Environment Mapping

It's from the wiki, there you also find an explanation etc.

And that's the code:

Code:

---

bmap bcube=<cube+6.tga>;

function mtl_envmap_view()
{
	mat_set(mtl.matrix,matViewInv);
 	mtl.matrix41=0;
 	mtl.matrix42=0;
 	mtl.matrix43=0;
}

function mtl_envmap_init()
{
 	//...maybe you should copy the mat_model properties here...
 	bmap_to_cubemap(mtl.skin1);
 	mtl.event=mtl_envmap_view;
 	mtl.enable_view=on;
}

material mtl_envmap
{
 	skin1=bcube;
 	event=mtl_envmap_init;

 	effect=
	 "
 		 texture entSkin1;
 		texture mtlSkin1;
 		matrix matMtl;
 		technique envmap
 		{
 			pass p0
 			{
 				texture[0]=<entSkin1>;
 				texture[1]=<mtlSkin1>;  

 				zWriteEnable=true;
 				alphaBlendEnable=false; 

 				colorArg1[0]=Texture;
 				colorOp[0]=Modulate2x;
 				colorArg2[0]=Diffuse;

 				colorArg1[1]=Texture;
 				colorOp[1]=blendCurrentAlpha;
 				addressU[1]=Clamp;
 				addressV[1]=Clamp;
 				texCoordIndex[1]=cameraSpaceReflectionVector;
 				textureTransformFlags[1]=Count3;
 				textureTransform[1]=<matMtl>; // transform camera space back to world space
 			}
 		}
 	";
}

Ok i tryed to add the code but i totally have no idea what to do next ^^ yeah im noob with shaderstuff ^^ ..should i call the mtl_envmap_init in main?

no you set my.material = mat_envmap to your object's action.

ah okej it works now its impressive this shaderstuff

does anyone know (where) can i find a manual for shader-programming? i wanno let the metal shine but still seeing the texture...its for a sci-fi game..to apply to a few doors and boxes and stuff

Here's a tutorial for using Environment Mapping with an Alpha Channel so that you can choose which parts of your model have a certain "metal shine"

http://homepage.sunrise.ch/mysunrise/lordsebe/envmap_tut_eng.htm

But it has been written a) by me, and b) a long time ago, so don't expect it to be easy to understand ^^'

Can anyone tell me where to get cube+6.tga?

thanks

thats a place holder. You can use any sky cube you like. Of course you have to rename the file to make it work.
