Cube Map from Render Texture

I am toying with the idea of a real time reflection on my main character while it is in one of its special golden modes. I would like to use something like the normal Diffuse Reflection shader, except give it a new cube map each frame. I currently just have a canned cube map which is basically some gold Cloud filter and noise and levels. Perhaps this would have to be combined with the real time reflection to give a sense of "gold" material.

Can anyone offer some direction?

Thanks,

At the moment, Unity does not support render-to-cubmap...

What I've seen a number of games do is one of the following:

* use a 2D texture with a very wide field of view rendered somewhere between the object that should have the reflections and the main camera. This can also be varied (= if the game is mainly top-down, render with a camera above the scene)

* Grab a portion of the screen somewhere the main object is not. Burnout3 uses this to great effect to do reflections for the player car.

You could also implement dual-paraboloid reflection mapping - that is essentially 2 2D textures getting the full 360 deg FOV using some funky projection matrix math (IIRC).

In either case, You then use a vertex program to calculate some texture coordinates that look 'good enough'.

Which game is this for?
