Corona Physical to Legacy

Lastest version: 1.08 | Updated: 06/03/2023

A small script to convert Corona Physical Material or General Physical Material to Corona Legacy Material (old Corona material class).

Note that, although it keeps most of the textmaps and parameters of the old material, the converted material can differ greatly from the original material depending on the settings. So please use with caution, save your file before pressing convert.

Support Corona Renderer 7 or higher.

HOW TO INSTALL

• If the file you downloaded is in ZIP format, extract it to get MCR installer file.
• Drag and drop installer fileinto 3ds Max viewport, no need to remove previous versions.
• You can find script button in Customize User Interface > Toolbar > D95 DESIGN.

HOW TO UNINSTALL

• Go to usermacros folder in 3ds Max ENU, and then delete the corresponding macros.
• Restart 3ds Max to take effect.

METALNESS MODE

• Autodetect: script will automatically detect the metalness mode of selected Physical material. If it is in metal mode, the IOR of the converted material will be set to 999.
• Keep only IOR value:  script will only keep the IOR value of the Physical material. Note that for Corona Physical materials, the IOR has a maximum value of 3, so if you use this option, the converted material will never have metallic properties because of low IOR.

THINGS TO CONVERT

• Everything in scene: convert all materials found in the current scene.
• Only selected objects: convert all materials found in the current selected object.
• Only selected materials: convert all selected materials in Slate Material Editor (SME).
