Realtime Updating Cubemap, won't work!

Graphics
1

Hello guys
I am trying to use the Unity3D reference posted source for realtime updating cubemaps, available here: Unity - Scripting API: Camera.RenderToCubemap
(The second source).
But I don’t know how to setup. I tried to put this script on my mesh which also have Mesh Renderer, and then I changed the material to Reflective/Diffuse.
But this does not want to render cubemaps and apply on the mesh. How can I fix this? Thanks.

do you have unity pro?

This seems to happen if you save the scene first and then hit play… usually fixes it for me…

Yes I have Unity Pro with also Android Pro, which is the target platform. I am going to try it without save before playing. My biggest problem is that I cannot stop my finger to press Ctrl S, it’s impossible! haha, I want to ask, does this work also android? Thanks guys, I will let you know in less then 1 minute!

No I don’t know why, but it didn’t worked!

Now I get this error:

and

What is?

        cam.transform.position = transform.position;
        cam.RenderToCubemap(rtex, faceMask);
    }

    void OnDisable()
    {
        DestroyImmediate(cam);
        DestroyImmediate(rtex);
    }
}

Here is the script that i use for my realtime reflections… just attach it to your object (or an object in a prefab)… it also handles culling and allows you to set the distance of the reflection…

Wow, amazing, thank you so much, this is looking working, also in Edit Mode, I am going to set the values and test it, thanks!!!
