Getting Started with VNS 2 Part 10. Post Processes


1. Post Processes are entirely new to VNS 2. Not only can we render many effects that were previously done in post, but you can also use project parameters to create effects that you can't do in post. Open the YNP9 project. Render the upper left Lake Sky view.

2. Go to the Render Task Mode and add a Post Process.

3. Name it Cartoon. Add Post Process Event and the type will default to Gamma.

4. Go to the Event Type dropdown list and select Chromax.

5. Select Preview Only and the render will refresh and preview the Chromax effect.

6. Add another Post Process Event. Choose Edge Ink from the Event Type dropdown list.

7. That's a bit too much ink, so decrease the Intensity to 20%.

8. Deselect the Event Enabled box to turn Edge Ink off.

9. Add another Post Process Event and select Text Overlay from the Event Type dropdown list.

10. Go to the Detail 1 page and change the Y Center to 90%.

11. Go to Detail 2 and type Lat: in the Text box.

12. Double-click Camera Latitude from the lower list to add it to the text string.

13. Type [space] Lon:, select, and add the Camera Longitude.

14. Type [space] Bearing: and add the Camera Compass Bearing.

15. Go back to the Detail 1 page and increase the Width to 150%. Save the project as YNP10.

16. Go to the General page and Add another Post Process Event. Choose Composite from the Event Type dropdown list.

17. VNS reminds us that best results are obtained if the composite is done before reflections are evaluated. That makes good compositing sense, so let VNS enable Before Reflections for you.

18. This is the new and improved way of compositing LightWave and 3DMax output with VNS. Create the project in VNS and Export Scene from the File menu to export it in LightWave or 3D Studio format.

19. Add animated objects to the LightWave or 3D Studio scene and render to RLA output. RLAs have both RGB image and Z-buffer depth information.

20. Open the Image Object Library to add the first RLA image as an Image Object. Give the RLAs a Sequence Attribute and they're ready to composite.

21. Go to the Detail 1 page and add the RLA sequence from the Image Object to Composite dropdown list. Read more about the new compositing process in the Interactive Reference Manual.

22. We're not going to use the Composite Event, so go to the General page and Remove it.

23. Confirm the operation.

24. Deselect Preview Only to allow Post Process rendering to file. Deselect Evaluate Before Reflections. Save the project.

25. Expand the Render Jobs and Render Options categories in the Scene-At-A-Glance.

26. Open the Cabin Final Render Job and rename it Lake Sky.

27. Change the Camera to Lake Sky. Edit the Render Options.

28. Rename it Lake Sky..

29. Go to the File Output page and Add a Targa Output Event. Name one AfterPost. Name the other BeforePost. Select Save Before Post Processing for the BeforePost event.

30. Go to the Post page and Add a Post Process.

31. Select the Cartoon item from the Post Process list in the Lake Sky popup window. Confirm the operation.

32. Go to the Miscellaneous page. Pixel Fragments are a big part of the reason that VNS 2 has new enhanced rendering features and improved render quality. If you're in a render time bind, you can decrease the Antialiasing Quality value, but do test renders before committing your changes to final rendering.

33. Open Render Control. Confirm the Camera, Options, and Save settings for the Lake Sky Render Job. Give the Render Job a Go. Show Rendering to view the render in progress.

34. When VNS is finished rendering, the Rendering Complete window will show one of the renders. Alt+] to view image from disk, and open the other image.
