Composite outside image using alpha channel workflow

[reptar]

Hi, i am after some reference regarding the workflow of compositing an outside image over my rendered window.

 

I have rendered a scene using 3D Max and have the alpha channels. I am getting confused with the workflow of compositing the outside image in Photoshop to appear as if it is outside the window.

 

Thanks

there's some great tutorials if you search for them on google for exactly this technique -

also you can look up masking too

 

good luck
