Kaizen analyses why some CG nature scenes are missing realism, and boils it down to three points:
- Scattering - Random, but not too random. Simulating naturally occurring clustering of types, and avoiding things like plants sticking through rocks.
- Shapes & Sizes - Adding different types of plants and stages of growth.
- Motion - Adding a gentle motion to avoid making your scene too static.
He uses the free GScatter add-on from Graswald (registration required) to illustrate these principles.
