    Hello,

    I know that normally when you use Grabpass on a shader, it takes whatever is behind the object and makes a texture out of it.

    However, instead of rendering what is behind the object, is it possible to render what is being seen by another camera?

    Thank you,
    Alex

    Sure, with a RenderTexture you can render a camera view into a texture and use it in whatever way you want. This is a pro feature though.

    Thanks! I would like to try a solution that doesn't require Pro, but it's good to know RenderTexture is available as a last resort.

    It's a pro feature if you're using Unity 4, Unity 5 there's no difference between pro and free in terms of available features.

    Ah, right, forgot they changed that. RenderTextures for everybody.
