Corona Render Elements Manager is a MaxScript for 3ds Max that automatically adds and manages Corona Render Elements. When launched, it checks whether Corona Renderer is installed and switches to the correct renderer, and it cannot be used without Corona Renderer. Its default selection is configured for basic composition.
The interface lets you adjust ZDepth and AO max distance values directly with a spinner. Adding a LightMix element automatically creates Light_ENV, a LightSelect with Include Environment light turned on, and Light_SUN, a LightSelect built from the scene's Sun when one is present. Buttons cover Select/Deselect All, Reset Selection to default, ON/OFF Filtering of existing elements, and Delete Existing to clear render elements from the setup panel. A checker can delete all existing render elements when you click Add, and the Caustics checkbox is available from Corona 4.
Installation is drag and drop into the viewport, followed by adding the script to a toolbar through Customize User Interface. Version 1.04 adds WireColor and Render Cryptomatte elements, and it is compatible with 3ds Max 2020 through 2025.
