BEGIN COMPOSITING AND POSTPRODUCTION

READY YOUR FILES TO START ENHANCING YOUR 3D RENDER

01

PLAN THE WORKFLOW

Having completed the render, it is now

time for compositing and post-production. It is

always essential to know how much you can get

directly from 3D and how much can you add

later, and in this case, the plan is to change the

background and enhance the image with the

render passes, and add some more detail by

using textures in Photoshop.

02

OVERVIEW THE FILES

This render was completed in Autodesk’s

3ds Max using the V-Ray render engine, but almost

all 3D software offers you the possibility to render

several passes, or render elements as they are called

in V-Ray, in order to help during your post-production

process. In this case, the documents consist of the

main render, Alpha channel, Reflection, Specular, Raw

Total Lighting, Wire Color and Normals.

03

USE THE WIRE COLOR

The Wire Color pass is extremely

useful, because it has all the separate objects

that were rendered, coloured differently. This

makes it very easy to make selections that

otherwise would be time-consuming and

tricky to achieve. This method of selecting

objects will be used intensively while

post-producing this image, in the next stages.
