This Cinema 4D plugin converts all Corona material inside a scene to C4D equivalent

The intent is to support FBX and similar file export and NOT to make a full material conversion. This means not all Corona features are supported. Because only bitmaps are supported by export formats, this plugin has focused on them.

Cinema 4D does not support materials during export if they are not internal. So this plugin tries to limit this gap.

It maintains all bitmap directly loaded into C4D Bitmap and Corona Bitmap shaders.

On the other hand, it not (yet) supports other kinds of shaders.

• Possibility to clean all old and unassigned materials after conversion (also sorting).
• Normal/Bump channel automatic assignment.
• Possibility to not discard all C4D original shaders.

Roadmap

In future (hope close) version 1.2.0 the following feature are in the workshop:

• Possibility to not discard all not supported shaders.
• Possibility to Bake all shaders(non bitmaps) into bitmaps.
• Choose Bake resolution.
• Support for more Corona material types.
• Automatic conversion of Translucency channel

Installation

• After downloading CoronaToC4D.zip file extract it into your Cinema 4D plugin folder (E.G.: “C:\Program files\Maxon CInema 4D R21\plugins”)
• At first execution you’ll be asked to fill with email and license key (you received by email)
  After that, you’ll never request for this info.

Remember that a license key is valid only on one machine.

If you reset your hardware or change Cinema 4D installation, plugin may not work.

You can contact us if the case.

Usage

You can open Options Dialog by clicking on the cogwheel near plugin icon:

Otherwise you can click on icon and execute it directly with chosen settings.

• Only Selected Materials
  Will convert only materials active in Materials view.
• Purge Old and Unused Materials
  At the end of the process will purge all unused materials.
• Skip C4D Shaders
  All C4D shaders different from Bitmap will be skipped.
• Sort Materials
  At the end of the process will sort materials in their view.
• Store Options
  You can Store on disk or Reset all settings in Options Dialog.

Example of conversion features:

NOTE: CoronaToC4D Material Converter acts only on materials assigned to objects (or if you prefer on objects with material tags assigned).
