How to Render 360 Panoramic Images in Blender

Panoramic camera projection is a method of mapping a full spherical environment onto a flat two-dimensional image plane, enabling the creation of immersive 360-degree visuals for virtual reality, interactive tours, and environment maps. This guide explains the core principles of panoramic projection and provides a step-by-step walkthrough for configuring and rendering equirectangular 360-degree images using Blender's Cycles render engine.

What is Panoramic Camera Projection?

Panoramic camera projection mathematically transforms light rays coming from all directions around a single point in 3D space onto a 2D surface. Unlike perspective projection, which simulates a standard lens with a limited field of view, panoramic projection captures up to 360 degrees horizontally and 180 degrees vertically.

The most common projection format for 360 imagery is Equirectangular Projection (also known as spherical or lat-long mapping). In an equirectangular image, lines of longitude are mapped to vertical grid lines, and lines of latitude are mapped to horizontal lines. This creates a distinctive distortion where the poles appear stretched horizontally, but the image correctly wraps into a seamless sphere when viewed in a 360-degree viewer or VR headset.

How to Render 360 Images in Blender

1. Set the Render Engine to Cycles

Blender requires the Cycles rendering engine for native panoramic camera projections, as EEVEE does not fully support equirectangular panoramic rendering out of the box.

  1. Go to the Render Properties tab (camera back icon) in the Properties panel.
  2. Change the Render Engine to Cycles.
  3. Set your preferred Device (GPU Compute is recommended for faster rendering).

2. Position and Align the Camera

  1. Select your camera in the 3D Viewport or Outliner.
  2. Move the camera to the desired viewing location (typically around eye level, roughly 1.6 meters above the floor for interior scenes).
  3. In the Transform panel (press N in the 3D Viewport), ensure the camera’s Rotation X is set to 90° (or 0° depending on your coordinate setup) and Rotation Y is set to 0°. Keeping the camera perfectly level prevents the horizon from curving unnaturally in 360 viewers.

3. Change Camera Projection to Panoramic

  1. Select the camera and navigate to the Camera Properties tab (green camera icon).
  2. Set the Type dropdown to Panoramic.
  3. Set the Panorama Type to Equirectangular.
  4. Leave the Field of View settings at their defaults:
    • Latitude Min: -90°
    • Latitude Max: 90°
    • Longitude Min: -180°
    • Longitude Max: 180°

4. Configure the Output Resolution

Equirectangular images must use a 2:1 aspect ratio to display properly without vertical or horizontal stretching.

  1. Open the Output Properties tab (printer icon).
  2. Set the Resolution X to an even power, such as 4096 px (4K) or 8192 px (8K).
  3. Set the Resolution Y to exactly half the X resolution, such as 2048 px or 4096 px.
  4. Ensure the Resolution % is set to 100%.

5. Render and Save

  1. Press F12 or click Render > Render Image from the top menu.
  2. Once the render completes, click Image > Save As in the Render Result window.
  3. Save the file in your preferred format. Use PNG or JPEG for standard viewers, or OpenEXR / Radiance HDR if you intend to use the image as an HDRI environment map for lighting other 3D scenes.

Tips for Better 360 Renders

  • Noise Reduction: Enable Denoise under the Render Properties panel to clean up high-frequency noise without requiring excessively high sample counts.
  • VR Metadata: If uploading directly to platforms like YouTube or Facebook for 360-degree viewing, inject standard spatial 360 metadata into the output file using tools like Google's Spatial Media Metadata Injector.
