In order for the Corona Converter to convert scenes created with other renderers and 3rd party plugins, those render engines and plugins must be installed in the 3D application, so that they are recognized. They don't need their licenses activated.

If you are converting scenes from V-Ray to Corona, you need V-Ray version 3 or newer. Older versions are currently not supported.

V-Ray specific objects, lights, and materials are supported only if V-Ray renderer is installed in 3ds Max.

Conversion

Conversion: Everything (materials, maps, lights) / Scene materials and maps only / Scene lights only / Materials of selected objects only / Selected material editor slot only / Selected material editor slot only / Show warnings / Convert CoronaLegacy MTL / - Selection modes convert materials and maps without breaking instancing, so be aware that other materials could be also affected.

Metalness Autodetected, force non-metal, force metal.

Convert Starts conversion.

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).

Corona Converter tried to keep as many of the original settings as possible in newly created nodes. 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.
