Render an image with multiple camera angles simultaneously on Blender
Step 1: Create a scene for every camera angle you’ll be rendering, and link your objects to all the scenes.
Step 2: Create a new camera for every angle, and on one of the scenes, enable compositing on the render panel.
Step 3: Finally, on your compositing node editor, check “use nodes” and duplicate your Render Layers input and assign your scenes to each, then connect each to its own file output. It should render the way you want it to.
