You can render an image of your model in the viewport or to a file. Realtime rendering shows a preview of your model's rendered image in the viewport, but Photo-realistic rendering generates a high-quality image, either in the viewport or to a BMP, TIFF, or JPG image file.
To render an image to the viewport,
1. Click View and then, in the Realism group, click Render.
You can keep the Rendering Settings dialog box open to try different settings as you render images to the viewport. Click File > Settings > Rendering Settings to open the Rendering Settings dialog box.
To render an image to a file,
1. Assign rendering elements to the model (such as render materials, light studios, backgrounds, etc.).
2. Click File > Render to File. The Render to File dialog opens.
3. Select the file extension from the Type menu.
4. Select rendering settings from the Settings menu.
◦ Use Photo-Realistic Rendering Settings: Use the settings defined in the Photo-realistic tab of the Rendering Settings dialog.
◦ Fast Rendering: Quickly generate an image.
◦ Accurate Rendering: Generate an image of the highest possible quality.
5. Select the pixel dimensions of the image file, or enter pixel dimensions in the Width and Height fields.
◦ If you enter your own dimensions, click Keep viewport aspect ratio if you wish to ensure that the width to height ratio of the generated image is consistent with that of the viewport.
6. Click Filename. The File Browser dialog opens.
7. Browse to the folder where you want the image file saved and type a name for it in the Filename field.
8. Click OK. The File Browser dialog closes.
9. Click Render to File.
10. Click Close when you are finished rendering images to files.
The JPEG output is based in part on the work of the Independent JPEG Group, and uses the sixth public release of the IJG library.
Limitations
Photo-realistic rendering can only be active in one viewport at a time.
If the current viewport is rendered, the activation of any modeling command or any viewport modification will terminate the photo-realistic rendering.
