Corona Converter

This page provides information on the Corona Converter, its settings, and usage.

Overview

The Corona Converter is a tool you can use to convert scenes made with other renderers to Corona. It automatically converts materials, maps, lights, and more. It is installed with Corona by default and can be launched using:

• The dedicated Corona Toolbar icon.

See screenshot

• The quad menu after right-clicking in any viewport.

Options

General Options

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 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).

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'.

Conversion

Everything – When enabled, the Converter converts everything in the scene.

Metalness

• 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.
