GETTING STARTED

● 3dsMax is a plug-in architecture

● CAD apps tend to have 3rd party SDK or need custom integration

● Web Based apps need linkage to server back end and exporters

● In-Store or custom apps are standalone .exe

BUILDING YOUR EXPERIENCE

● Initialise, paths, install area, render plug-in

● Pass initial geometry and fit the camera

● Work on the camera

● Make some basic material transfers to test transfer

GEOMETRY

● Polygons, Meshes, Meshes with Holes, Surfaces

● Instances

● Groups, Sub Meshes/Smoothing Groups

● Texture UV Mappings

CAMERA MATCH

Geometry and Camera can often

most challenging part of an

integration

Important to get this right before

progressing.

BASIC MATERIAL MAPPING

Validate your geometry transfer

by pulling basic Materials from

the application

3DSMax has quite complex

internal materials. For now we

take colours and textures of first

texture channel.

Now we can start to have some

more fun!
