Clearcoat Newton’s Rings simulates the interference of light between a clearcoat layer and the underlying material, producing concentric, rainbow-colored rings commonly seen in very thin films.
Variations in the film’s thickness can be controlled with a Thickness Map (Grayscale) thickness texture, which can be painted in Toolbag using a Texture Project or created in third-party applications.
| Setting | Description |
|---|---|
| Thickness Map Texture Slot | Add a thickness texture by clicking on the slot or dragging and dropping one from the Library. |
| Channel Selection | Determines which channel of the texture map will be used. It’s useful when, instead of using multiple single textures, you use one texture with different grayscale maps in the different texture channels: Red, Green, Blue, and Alpha. |
| Strength | Sets the intensity of the interference effect. |
| Film Thickness | Controls the thickness of the outer surface layer. This affects the interference pattern, as higher thicknesses display more “rings”. |
| Minimum Thickness (mm) | Sets the lower bound thickness corresponding to the lowest value in the thickness map. |
