Stage 1: AutoCAD Drawing
In stage 1 on this project, surfaces are created from an accurate landform mesh made from 2D and 3D polylines using Key 3D surfacing routines.

Stage 2: Create Landform Mesh
This tutorial takes AutoCAD groundmodel data and uses it to create a landform mesh in 3ds Max with Key 3D.

Stage 3: Create Surfaces
Production of seamless surfaces for roads, pavements, grassed areas and planting beds is probably the most important stage in the creation of a 3D landscape scene. This tutorial shows you how.

Stage 4: Create Kerbs
Edges are often created using the Loft compound object instead of a simple extrusion to take advantage of the loft mapping parameters. The Loft mapping parameters enable kerb or brick materials to follow the curves of an edge as they do in the real world. In this example a kerb is created using Key 3D Edge Path and Key 3D Edge Section.

Stage 5: Create Houses, Roadlines and Fences
Elements of a scene such as houses are classed as "Objects". Objects are items that sit on the landform terrain or conform to its surface. They are usually positioned in AutoCAD using blocks or lines. This stage describes the process for creating houses (including roofs), fences and road lines.

Stage 6: Lighting and Shadows
Lighting outdoor scenes involves the setup of a Sunlight or Daylight system, together with ambient light. This tutorial uses Key 3D Sunlight and Shadows to automatically setup a Sunlight System with some environment settings and including the use of a Key 3D Light Dome for added natural ambient light.

Stage 7: Setup Views
Key 3D uses ONE camera for still views. This is tied into Image Object functionality where images of people and trees and shrubs are mapped onto planes and "look at" the camera. This tutorial explains how to setup views using Key 3D View Manager.

Stage 8: Assign Materials and Sky background
When surface and edge modelling has been completed and the lighting has been setup correctly, materials can then be assigned to surfaces and edges. This tutorial guides you through the process.

Stage 9: Replace blocks for Lamp Posts and Trees
Simplified blocks for lamp posts and trees in the AutoCAD drawing can now be imported and replaced with 3D models and images using Key 3D Model Objects and Image Objects dialogs.

Stage 10: Add Play Equipment, Vehicles and People
Finally, Key 3D Model Objects dialog is used to add play equipment, cars and vans and Key 3D Image Objects dialog is used to add people. This brings the scene to life and further adds to the sense of scale for the design.

Stage 11: Rendering
In this final stage of the project, views created with the Key 3D View Manager are rendered using Supersampling for best quality.
