how to make background dissapear

[carlangas]

Hi all,

 

I am doing an exterior using an hdri image as an instance in the vray enviroment and in the max background (the one that shows up when you press 8). i do want the hdri to be shown in the glass reflections but dont know how to remove the sky from my final image for compositing. before I used vray and hdri I would just save the final image as a tga file with an alpha channel so when I opened it in ps the sky would be gone. how do i achieve this using vray and an hdri?

 

thanks.

Why R U using it in the max background?

I usually use it in vray's environment AND reflections....save as tga and get as a transparent image....

and/or, when you save the file check "store alpha channel." then change it in photoshop.
