Width and Height

Specify the width and height of the saved image in pixels. Click the Use Screen Size, Use 2X Screen Size, and Use 4X Screen Size buttons to update the Width and Height values automatically.

Constrain Proportions

Locks the Height and Width values to each other so when one value is changed the other is updated to maintain the original aspect ratio. When off, you can adjust the Height and Width values independently and output an image with different proportions compared to the default setting.

Use Screen Size

Exports the image at the same resolution as the 3D View. (Automatically updates the Width and Height values.)

Use 2X Screen Size

Click to save the image at twice the resolution of the 3D View. (Automatically updates the Width and Height values.)

Use 4X Screen Size

Click to save the image at four times the resolution of the 3D View. (Automatically updates the Width and Height values.)
