Accurate Environment Lighting

You can apply accurate environment lighting to clean up excessive noise in renderings.

The benefits of using accurate environment lighting are:
  • Accurate environment lighting calculation from custom high dynamic range images, HDRI, used for scene environments.
Use accurate environment light when:
  • Shadows in the current rendering are too noisy.
  • You use a custom HDRI image to define the scene and you need more accurate lighting from the custom HDRI image.

Apply the accurate environment lighting when you refine renderings using the PhotoView 360 preview window.

When you use this setting, it can significantly slow down rendering.

To apply accurate environment lighting:

  1. With a model open, click Tools > Add-Ins and add in PhotoView 360.
  2. From the DisplayManager, click View Scene, Lights, and Cameras .
  3. Right-click Scene and select Edit Scene.

    To view the document scene you must set the background appearance to Use document scene. Click Yes to set the background appearance, if the Background Display Setting dialog box appears.

  4. On the Illumination tab, under PhotoView Illumination , select Accurate environment lighting.
  5. Click PM_OK.gif.

Refining Renderings

You can save renderings in progress directly from the PhotoView 360 Preview window.

You can use the extended refinement settings in the PhotoView 360 Preview window to refine the rendering beyond the specified quality setting in the PhotoView options. The quality of the rendering increases over time. You can also specify that the PhotoView 360 Preview window create an image that uses the full specified output image size in the PhotoView options.

Use continuous refinement with the Accurate environment lighting option to get the best results.

To refine renderings:

  1. Click PhotoView 360 > Preview Window.
  2. Choose how you want to do the rendering:
    • Extended refinement to force the preview to refine beyond the specified quality settings in PhotoView options.
    • Full resolution preview to force the preview to render an image that is saved at the size specified in PhotoView options.
  3. Click Save Preview Image to save the result displayed in the PhotoView Preview window at any time.
