To introduce some reflectivity to the material, enable "Reflection" property. This makes it useful for basic materials such as plaster, painted walls, and similar. It is gray with a diffuse level (brightness) of 70%. The default Corona material has diffuse component only. To create a new Corona material go to Corona > New Material in the material library panel. The C4D file containing simple materials presented in this guide can be downloaded here: Please visit the following link to learn more about it: Note: Starting from Corona Renderer 7, the Corona Material has been renamed to Corona Legacy Material and you will find a new and more complete material called Corona Physical Material which will allow you to create more accurate and realistic materials for your projects.
