4D Publish | Exporting Channels
Export the Color Channel.
If this option is disabled, or there is nothing in the color channel, then it will use the Objects color if it is enabled in the object settings.
If Use Color is off, and there is nothing in the Color Channel, it will set the color to be Grey (50%).
The following shows some uses of the Mix Modes and color settings that are supported. The Normal mode is fully supported, however other modes such as add, subtract and multiply, are supported as best as can be so that they are as close as possible in Acrobat Reader as they are in C4D. Results may vary however.
