Manual

The script is quite simple to use. In the current version, the script has only 2 options:

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).
