Preview cubemap rendertexture on screen

Questions & Answers

I know how to make a cubemap with a RenderTexture, but how can I set this cubemapped RenderTexture as a GUI image to preview it in my game?

Normal GUI images work, but this cubemap doesn't show. Only a white rectangle is shown.

Try casting:

public RenderTexture cubeMap; // Assign through inspector
public GUITexture blank; // Assign a blank GUITexture here
Texture2D drawTexture = (Texture2D)cubemap;

void Start() { blank.texture = drawTexture; }
