Add prefix to converted material – Adds a prefix to name of all converted materials.
mr. Area Light/Lights to Corona Light(s)– Converts mr Area Omni Light and mr Area Spot Light to CoronaLight.
Bitmap(s) to CoronaBitmap(s)– Converts Bitmap texture maps to Corona Bitmaps.
Enable "Thin shell" if translucent– Enables Thin shell parameter of the converted material, if the original material was translucent. Physically based materials in Chaos Corona are only allowed to use translucency effects when describing objects with Thin Shell.
Switch to Chaos Corona– Switches active renderer of the current scene to Chaos Corona.
V-Ray specific options
Convert VrayHDRI(s)– Converts VRayHDRI(s) - texture maps to standard Bitmap texture maps.
Convert V-ray proxies– Converts V-Ray proxies to Corona proxies (opens a pop-up dialog with further options during the conversion).

V-Ray specific objects, lights, and materials are supported only if V-Ray renderer is installed in 3ds Max.
Individual tools
Reset Compact Material Editor materials– Resets all Compact Material Editor materials to default CoronaPhysicalMTL(s).
Show statistics– Shows statistics about CoronaPhisicalMtl(s) in the scene.
Convert by class– Converts specific unsupported materials classes to default CoronaPhysicalMtl(s) (e.g. missing_mtl or Maxwell materials).
Selected objects' maps in viewport
Show– Workaround for displaying diffuse maps in the viewport.
Hide– Workaround for turning display of diffuse maps in the viewport off.
Disable CoronaRoundEdges maps Legacy behavior– Disables Legacy behavior of all CoronaRoundEdges maps.
Fix CoronaNormal "Incorrect gamma" warnings– If some CoronaNormal node displays Incorrect gamma warning, tries to fix it by switching its add gamma to input option on or off. Only works if the input texture's gamma is either 1.0 or 2.2.
Convert VRayDispacementMod(s) to CoronaDisplacementMod(s)– Converts VRayDispacementMod(s) to CoronaDisplacementMod(s).
Bitmap(s) - > CoronaBitmap(s)– Converts Bitmap texture maps to CoronaBitmap.
CoronaBitmap(s) - > Bitmap(s)– Converts CoronaBitmap(s) to Bitmap(s).
Set normals filtering
None– Set all CoronaPhysicalMtl and CoronaSkinMtl materials to use normal filtering mode 'None'.
Linear– Set all CoronaPhysicalMtl and CoronaSkinMtl materials to use normal filtering mode 'Linear'.
Roughness mod.– Set all CoronaPhysicalMtl and CoronaSkinMtl materials to use normal filtering mode 'Roughness modulation'.
Everything – When enabled, the Converter converts everything in the scene.
Scene materials and maps only – When enabled, the Converter converts materials and maps only.
Scene lights only – When enabled, the Converter converts lights only.
Materials of selected objects only – When enabled, the Converter only converts the materials of the currently selected objects.

Conversion selection modes convert materials and maps without breaking instancing, so be aware that other materials may be affected by the conversion as well!
Show warnings – When enabled, the Converter shows warnings during the conversion process.
Convert CoronaLegacyMtl – When enabled, all Corona Legacy Materials in the scene are converted to Corona Physical Materials. When disabled, they remain as Corona Legacy Materials.

Autodetect – Corona attempts to automatically detect whether a material should be converted to a metal or non-metal. This may not always be accurate, so some manual adjustments may be needed after the conversion.
Force non-metal – All scene materials are converted to non-metals.
Force metal – All scene materials are converted to metals.
Convert– Starts the conversion process.

Corona Converter tries to keep as many of the original settings as possible in newly created materials. For Refractive, Translucent, and Volumetric materials sometimes there will be more nodes than in the original material. Nevertheless, the Converted materials will look and render just fine.
