How to create a refraction plane in the BGE? I need a refraction plane.
What refraction script should I use to create many planes?

Imagine what every plate is window made with similar to RenderToTexture script. For ex.: I want to create house and add 3 windows made of similar to Render To Texture script. And the main question is: How many planes can I use with this script? Do I need other script for it, bit more advanced? Please, suggest me any possibility solution. :)
The only limit of this script is your Hardware configuration (RAM, GPU, CPU).

You can use the fake reflections too, with a texture and in the Texture pannel, replace the Mapping Coordinates to "Reflection" (Use GLSL for see in real time).

Many games use the fake reflection, but the camera may move for see the correct fake reflections.

Here a blend with reflection texture that i made (Gold texture):
