In order to allow color changes within the Colorway application, the exporter attempts to work out the resulting color of lights and part materials in your scene. These are reset to white for the render to allow full adjustment in Colorway. This message is displayed if the material setup is complex or contains procedural textures and the exporter cannot determine an accurate final color. As a result, some coloration may remain in your render, and adjustments in Colorway are limited. If you wish, you can uncheck the Allow Procedural Textures option in the Export dialog, and colorway removes any textures that it cannot represent when rendering.

In order to allow color adjustments in Colorway, the colors of lights and materials are reset to white during rendering. If the current color is set to a particularly dark value, then this neutralization may increase the brightness of the object in renders by such an amount that clipping occurs.

One way to work around this is to use reduced brightness, instead of a dark color to decrease illumination or object color.

Some of the C4D lights – for example the Physical Sky and Environment lights – do not have straight-forward brightness or color controls. As such, these are always exported to Colorway as is. This means it is not possible to change the existing color in Colorway - instead you can add an additional tint. It also means that with round-trip, adjustments may not re-apply correctly back in C4D.

As global illumination renders in C4D consider both the color and luminance values of the material attached to a Sky object, in a complex fashion, Colorway is unable to allow full color control of Sky lights within the application. This means it is not possible to change the existing color in Colorway - instead you can just add an additional tint. It also means that with round-trip, adjustments may not re-apply correctly back in C4D. If the Color channel is disabled, then more comprehensive adjustments are possible.

Colorway requires that C4D renders are performed in the linear color space. If you don’t have Linear Workflow enabled in your Project Settings, you can still render but renders can have a gamma shift in Colorway, and texture placements may be distorted. See the C4D Help if you are unfamiliar with this option.

In Colorway, each part can have a single material assigned at any one time. If you combine multiple C4D objects into one part, they should all share the same material. If you have more than one material assigned to the part’s objects, this message is displayed.

The color and textures you see in Colorway are taken from the named material. In some cases, this is fine, and as intended. For example, say you used two Materials, with the same color, but different specular properties to make some objects more shiny than others. If, however, you have assigned several shaders with different colors, it is unlikely to get the expected result in Colorway, as all objects take the color of the named shader.
