Making environment maps invisible in render?
show user profile  Nithel
I'm using a glossy mental ray Arch & Design material on my objects, and a HDRi bitmap in the environment Map slot to generate the reflections.
Is there a way to make the environment map NOT show up in the background of my render, but still be reflected in the material? I just want it to render as an alpha that I can save in my .png, so I can replace it with a background in Photoshop.

Use the environment / background switcher material.

However, the environment background shouldn't turn up in the render when saved as a PNG with alpha, once the image is opened in Photoshop. You will probably find that what you are doing is ok.

I didn't show up in photoshop, but I checked the alpha toggle in the rendered frame window, and sure enough there was one. Turns out I didn't check the "save alpha" when saving the .png.

Thanks for the help! And that environement/background switcher will surely come in handy one day :-).

if you want the environment on your object only, go to the mental ray Connection tab of your material and unlock the Environment option and select the Environment(3dsmax).
hit the Map button and get your image.

go to Render, Environment and r-click, clear that map you had in there.
This way the environment only shows up on the object.
