Render Settings Preferences - File Output tab
In the Menu Bar, click Edit > Preferences, then on the left side of the dialog box, select Rendering > Render Settings. After making any changes, press Apply and Save to save them.
Image
Default Format - Determines the default rendered image format.
Image Size Presets - Sets the resolution width and height in pixels for images rendered to disk. Use the drop-down list to select from standard resolutions.
Image Size - Defines the height and width in pixels of the image.
Printing Size - Displays the physical image size in millimeters and calculates it using the resolution and image size values.
Resolution - Defines the image resolution in dots per inch.
Supersampling - Enables the increase of antialiasing quality. This may impact performance.
Stereo Mode - Determines the rendered stereo mode settings. Options include Mono, Stereo, 5 Eye Stereo (five images), and 9 Eye Stereo (nine images).
Compression Quality - Sets the compression quality of an image by percentage. This only applies to image formats that support compression, such as JPG. For no compression, enter -1.
Framebuffer Limit - Sets the rendered framebuffer memory limit to ensure it is not exceeded.
Export Image with Alpha Channel - Renders the alpha channel into the resulting image, if the file type supports it. You can select the alpha channel color separately.
Show Rendered Image after Saving - Opens a separate window, showing the rendered image.
Single Image Viewer Window - Shows only one image per window.
Ignore Aspect Ratio - Squashes or stretches the rendered image and ignores the aspect ratio.
Export TIFF/PSD in HDR Format - Toggles the export of TIFF/PSD in HDR format on or off. Exports the HDR format as TIFF/PSD (32 bits per channel), when enabled.
Export EXR in 16 Bit Float Format - Toggles the export of EXR in HDR format on or off. Exports the HDR format as EXR (16-Bit Float), when enabled.
Export Multi Layer EXR/PSD for Render Passes - Toggles the export of Multi Layer EXR/PSD in HDR format on or off. Exports the HDR format as Multi Layer EXR/PSD, when enabled.
Renderpasses
Use these options for generating the depth pass in a linear scale, either using world space (Linear) or within a specified range (Normalized Linear & Normalized Reversed Linear), independently from the camera near and far clipping plane settings (Standard). Use depth of field or fog in post processing. Use Occlusion Range for tweaking contrast of creases in post processing.
Depth Pass Mode - Sets the way the depth pass is calculated. Choose from:
Standard - Writes a 1/z calculation, based on the OpenGL depth buffer calculation, to the depth pass. The near plane clipping maps to white, while the far clipping plane maps to black.
Linear - Writes a world space depth value to the depth pass.
Normalized Linear - Writes a linear depth value to the depth pass. The minimum value maps to black and the maximum to white.
Normalized Reversed Linear - Writes a reversed linear depth value to the depth pass. The minimum value maps to white and the maximum to black.
Depth Pass Range - Sets the depth minimum and maximum values when using either the Normalized Linear or Normalized Reversed Linear depth mode.
Occlusion Pass Range - Sets the range used for the ambient occlusion calculation. Use this to tweak contrast of creases in post processing.
Animation
Use these controls to set the start frame, stop frame, and frame rate for your animation. You can export a series of images or an AVI movie.
