[how] Need for Speed Underground looking road

[DarekRuman]

I actually managed to get a "mirror" shader working from zak's Water shader. From there on you should have everything you need in order to make a super reflection

Any code? samples?

Already got myself shader for cubic reflecion :



You can see ground and green box reflecting in my car. I'll post shader (modified for work in tv) if you wanna.

But i still need reflection for my road mesh - waiting for some tips from you guys.

I just use a water plane without movement and it creates a clear reflective surface, then I only render reflection, not refraction.

Sure would like to see your shader though, please post if you can.

Careful though. CubeMapping-based reflection and Planer-based reflection are incompatable. If you try to have the car reflect the reflected ground, your going to have artifacts, as shown here:

Actually the shader code was quite basic, it had nothing special. It's mainly the rendering code before it.

Zak uses a matrix trick, he's basically rendering the scene upside down. He also sets a plane so that the reflection is clipped at some point. Once the upside down scene has been rendered onto a rendersurface, this RS is passed as a texture into the water plane mesh shader. That's all I can remember at the moment, I don't think I have that code anymore.

OK - got myself something like this :



car reflection + road reflections (only buildings reflecting right now), all solved by shaders

That looks very sweet! I love the car shader.
The road looks very wet, but if that's the intended effect then it works very well.
