Getting Started
with VNS 3: Fields
& Forest
Part 5I. Realtime Foliage
1. There may be times when you
want to see Ecosystem foliage in realtime views. Because of the
possible resource load involved, it's not recommended that you
enable Ecosystem Realtime Foliage without first changing
the Preferences. Open the popup menu and select Realtime Options
> Land Cover > Realtime Foliage File Preferences.
2. Change the Distance Criteria
Far value to 500 meters and the Height Criteria
Minimum to 5 meters. Close the window.
3. Open the YNP Main popup
menu, and select Realtime Options > Create Realtime
Foliage File.
4. VNS will render a preview,
less sky, to generate the foliage file.
5. When the render is finished,
switch the YNP Main view back to realtime mode. Open the
popup menu again and select Realtime Options > Load
Realtime Foliage File.
6. The view will refresh with
realtime foliage.
7. Open the popup menu and Edit
View's Camera to open the YNP Main Camera Editor. This will set an undo point for the
camera moves we're about to make.
8. Slowly move the camera forward.
Your view response will probably be sluggish.
9. Realtime Ecosystem Foliage
can be handy for knowing where foliage is going to render. Use
it judiciously, though; the resource cost is high.
10. Go to the Camera Editor and Undo 
changes to return your camera to where it was when the editor
was opened.
11. Open the YNP Main
popup menu and select Realtime Options > Load Realtime
Foliage File to unload the foliage file.
12. Save the project and render
a preview.
