how to get refraction effect in game engine?

i saw the “cube map demo” thread, but seems to not use normalmap textures for refraction effect.

i want to apply to a plane a refraction effect with a normalmap texture. we can do it?

if the answer is yes, we can use this effect in the current Game Engine contest?

thanks.

nobody know…? :frowning:

i recently updated CubeMap demo… now it has normal map distortion effect also.
But the refraction/reflection is just a pre-Baked texture, so it wont really look good on dynamic object, you could take a look at Videotexture as it renders a txture from specified camera.

ahh…thanks! i will take a look to it.
