Hi everyone, I know this might sound like a dumb question, but I’m making a car and I’m using Cycles and I’m using an HDR image as the environment in the World settings to get reflections on the car, but I was wondering how I could save the final rendered image without including the HDR background because it’s looking really ugly in the final render and I just want to save the image of the finally rendered car without the HDR background. So, how exactly would I do this? Thanks for any help.
Hi,
At the bottom of the render panel you can check the box “transparent” (film tab). Then you can save your image as .png. Don´t worry about the black background, it will be transparent.
Thank you.
How can I do this in an animation rendering? And not for individual images/renders?
There is no difference in between rendering a single image or an animation. For Blender, a single image is like an animation with only one frame. Of course, what I say is valid only if you don’t render your animation directly in a video format. Who does that any way? Besides, I don’t know many video formats which support an alpha channel… (Just don’t forget to set the output format to RGBA.)
What was the question already? 
And if you want higher precision colour, you can use either TIFF or OpenEXR.
