simulating a reflective floor

I´m trying to simulate a reflective floor, right now I´m using the script for realtime cubemaping in the documentation found in here..

http://unity3d.com/support/documentation/ScriptReference/Camera.RenderToCubemap.html

The problem I have is that the reflection seems to ignore the walls or other obstructing geometry. The reflections happen but I can see relfections that happen in other rooms. Maybe I´m not understanding correctly what this script should do.

 

For a reflective floor you want to use some other script similar to the water. I think there is one on the wiki called mirror reflection or something.

Render to Cubemap should be used for reflective objects like vehicles or other things like that.

 

I think I understand my problem a little better now, I´m using a cubemap, the cubemap wraps around the object in this case a plane that represents the floor, but the cubemap never changes since I´m never moving the plane...

Anyone have any idea how to make a reflective floor?, I tried the mirror shader + script but that one doesn´t seem to recieve any shadows and I need shadows...

 

Probably the easiest way is to modify the mirror reflection shader to receive shadows. You would take the first step on that by downloading the built in shaders and looking at how they do it.

Another way is to make a copy of your room geometry and invert it along the Y axis at ground level, then use a transparent shader on the floor.

 

Thanks for the replys guys! I'll give those a try.

 

That worked like a charm, thanks a lot guys!!!!

 

Opps sorry, I didn´t realized how huge the image was up until now, I just put it up...., I´ll find a smaller one.

 

Ok, it works for the most part the shadows and reflections show up if my floor is in the default layer, if I put the floor in the water layer I lose the shadows. If I add water (I´m adding day light water) the reflection stops working or works partially...

 

Quick question.

By default this was a perfect mirror, but I would like to have the mirrored image to appear a lot darker.

So I changed "white" to "grey" and found that it was allready a lot darker, but could somebody please help me a little to help the shader below to even be DARKER? Like instead of white I would prefer rgb(50,50,50) fully opaque to be the base color.

Sorry, but I'm absolutely a big ZERO when it comes to shaders


Shader "FX/Mirror Reflection" {
Properties {
_MainTex ("Base (RGB)", 2D) = "grey" {}
_ReflectionTex ("Reflection", 2D) = "grey" { TexGen ObjectLinear }
}

// two texture cards: full thing
Subshader {
Pass {
SetTexture[_MainTex] { combine texture }
SetTexture[_ReflectionTex] { matrix [_ProjMatrix] combine texture * previous }
}
}

// fallback: just main texture
Subshader {
Pass {
SetTexture [_MainTex] { combine texture }
}
}

}

 

Ah great, then I'll experiment with that.

Thanks,

Bart

 

Is there a way to turn the reflectivity down? Right now, I've got a texture, but the reflective floor is too reflective; too glossy. Can I reduce it so that it looks like my floor is slightly reflective rather than a mirror with painted wood slats ghosted on the surface?

I've looked through both the .cs and the shader, and can't quite figure where to adjust for that....

 

Never mind. Tried the solution posted here: http://forum.unity3d.com/viewtopic.php?p=54287#54287

and it works great.

 

"The shader would need to be turned into fully pixel-lit one to receive shadows. "


how do u do that? i have unity pro

i selected shader and i got "per-pixel lit, cast shadows, render queue"etc. but they are all greyed out.

"open compiled shader" does nothing

what am i doing wrong?

 

I want to use StrumpyShaderEditor to generate my own shader based upon the reflection texture generated by wiki.unity3d.com/index.php/MirrorReflection3.

But I don´t know how to setup the nodes.
Can anyone help me here?
