How to use the Corona Material Library? - 3ds Max – Chaos Help Center

Corona Material Library - "Carpets" materials example

What is it?

The Corona Material Library was introduced in Corona Renderer 1.7 as a part of the installation package. It is downloaded automatically during the installation, but can be also installed manually in offline mode.

It provides hundreds of ready to use materials, each with a high quality preview. The library in is mainly intended for beginner users and those having problems with setting up basic materials, but may be as well useful to advanced users. The most common uses of the material library include:

Quickly painting scene objects with realistic materials (this can greatly speed up your workflow!)
Using the material presets as bases for creating own ones (great for users inexperienced with material creation and introducing variation in the scene)
Using the material presets as references for creating new materials from scratch (great if you are having trouble setting up a specific material)

How to open it?

You can find the Material Library:

In the Corona Renderer Official Toolbar:
In the Scene tab of the Render Setup dialog:

What are its features?

View materials by category
Set and view only favorites
Drag and drop materials into the viewport, Slate and Compact material editors
Assign a material to the objects selected in the scene
Select all objects in the scene that use a certain material
Most of the materials are using the Real-World Scale mapping so you do not have to worry about the correct scale and tiling
Many of the materials don’t need UV mapping, as they use the Corona Triplanar map
It can be installed in offline mode

Material Library updates in Corona 8

33 new materials in Nature category
9 new materials in Plastic category
13 new materials in Glass category

Future improvements

As with other features of Corona Renderer, we are planning to improve the material library in the upcoming versions. This mainly includes the ability to add your own material presets and categories, and to organize them according to your needs. Further ideas include:

Ability to easily scale textures and material properties (scale of the triplanar map, displacement, absorption,...)
Indication whether a material is using Real-World Scale UVW mapping or Triplanar mapping
Easier way to store the material library data on a network drive
More material presets
UI improvements

Why are some of the materials using the Real World Scale option, and others the Corona Triplanar Map?

Materials using both of those solutions should be used in slightly different situations. For more information, see this forum thread: [link]
