Reflaction map

hi,
some one can give me a code of Reflaction shading??

thanks!

hi
here is my german 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;
textureFactor=0x90FFFFFF; // -> C0=75%, 80=50%, 40=25% (alpha)
colorOp[1]=blendFactorAlpha;
addressU[1]=Clamp;
addressV[1]=Clamp;
texCoordIndex[1]=cameraSpaceReflectionVector;
textureTransformFlags[1]=Count3;
textureTransform[1]=<matMtl>; // transform camera space back to world space
}
}
";
}

action cubic
{
my.shadow=on;
my.material=mtl_envmap;
}

its very nice effect but i didnt ment this i ment reflaction like mirror

Use the A6 Pro's mirrors to make flat surfaces reflective. True reflections on models and such is way way too costly on the fps for real time games.

but i want to apply mirror on entity...
there is some way to get reflect what you see?
without env_map?

i'm pretty sure you can't do realtime reflections on entities without CEM (Cubic Environment Mapping)

Julian

you could make a realitme screenshot (not really a shot but camera .views) every frame and render to texture the result.

I think marco did somehting like that a time ago with a ball......might ask him for help.

I tryed that with a cube
and it is a bit slow..but its cool

Yes, Marco wrote a tidbit for RenderToTexture on entities a while ago for lower Gamestudio versions. (Though A6 Pro already has the feature I believe).

Also, Cubic Enviromental Mapping is just a fake, it doesn't actually create realtime reflections.

if you cant find anything maybe some one have code to Water-Shader?
