Render Textures and Lightmaps

Hi,

I am having somme issues with Render Textures.
I am currently using them in my game after instantiating a Camera prefab and assigning it a Render Texture, and then displaying the Render Texture using a GUI.DrawTexture().

However, I noticed that the lightmaps are not used by the cameras I instantiate, but they are used by the main camera.

Does anyone has a solution for this issue ?
