- Navigate to your saved view for rendering. If you don't yet have a saved view, please consult Rhino 5.28 [saved views] to create one.
- Show the camera for the saved view. (Right-click on the saved viewport's name and choose "Show Camera" from the context menu)
- Navigate to another view so that you can see the camera. In the example below, I'm looking at the top view.
[Premium Content - Login] [Membership Options] - Type distance into the command line and measure the distance from the camera to the closest object in the rendered scene. Make a note of this distance, you will need it later. For more information about cameras, consult Rhino 5.29 [cameras].
- Next, use the distance command again to measure from the camera to the furthest object in your rendering that you would like to have in focus. In the image above, I chose the back of the building.
- Open the VFB Channel drawer in the V-Ray Options dialog box. Confirm that Z-Depth is selected as one of the VFB channels.
- In the Z-Depth "Black" value box, enter the measurement you found in step 4 above. In the Z-Depth "White" value box, enter the measurement from step 5 above.
[Premium Content - Login] [Membership Options] - Make sure "clamp" and "set from camera" are unchecked.
- Perform your rendering and save all VFB Channels.
- Note: You will need to adjust these values for each rendering you perform as the distances from the camera to foreground and background objects will vary depending on the camera/rendering viewport.
- Follow Photoshop 1.25 [z-depth] to adjust the focal length of your final renderings.
