Parameter
Ribbon path
The Ribbon path tool allows you to create patterns that deform along a curve defined by points on the surface of the 3D model. The Ribbon can also be used to write text along a curve.
The Ribbon tool can be selected from the Path tool menu in the toolbar:
Or via the Path type button:
Overview
The Ribbon path tool differ from the Paint along path tool in how it draw images and materials.
While with the Paint/Brush based tool an image is repetated multiple times on a path, with the Ribbon the image repeated alongside the path and deformed to follow it curves. Individual component of a Paint brush are called stamps, while those in the ribbon are called patches.

Description |

|
Stroke width |
Control the global width of the current stroke. |
Opacity
|
Parameter |
Description |
|---|---|
|
Stroke opacity |
Control the final opacity of the current stroke. |
Stroke
|
Parameter |
Description |
|---|---|
|
Image orientation |
Define the direction of the input image. This direction will control how the image is put alongside the path. |
|
Flip image |
Flip the image along the axis/width of the path. |
|
Corner |
Define how broken corner (split tangents) should result on the path. Possible behaviors are:
Below are what the corner looks like, in order:
|
|
Omit ends when closed |
If enabled, the start/end sections will be removed when a path is closed to make a continous loop. This applies to both stretch offsets and dynamic strokes. |
Stretching & Tiling
The Ribbon path can use two different modes to control how an image is repeated and stretched along a path:
- Stretch along path: (default) the image repeated along the path will be stretched to fit the path length
- Keep aspect ratio: the image repeated along the path will have its aspect ratio preserved. If the image is too long compared to the path it will be cropped.
Stretch along path
|
Parameter |
Description |
|---|---|
|
Stretch between offsets only |
If enabled, allows to keep the start and end sections of an image intact while stretching the middle. Use the Start offset and End offset parameters to defined the size of these sections. The middle section will be implicitely computed based on the start/end.
|
|
Tiling mode |
Define how an image is repetated or not along the path. Possible values are:
|
|
Tiling amount |
Specify how many times an image is repeated in Custom tiling mode. |
|
Mirror every 2nd tile |
Flip the image used along the lenght of the path every second repetition. |
|
Aspect ratio factor |
Stretch or squeeze the current image aspect ratio. |
Keep aspect ratio
|
Parameter |
Description |
|---|---|
|
Ratio |
Define how the image is scaled while preserving its ratio:
|
|
Remove clipped tiles |
If enabled, will remove repetitions along the path that cannot be fully visible (if they are cropped). This setting is disabled if the Ratio setting is set to Fit to path length.
|
|
Tiling mode |
Define how an image is repetated or not along the path. Possible values are:
|
|
Mirror every 2nd tile |
Flip the image used along the length of the path every second repetition. |
|
Alignment |
Define where the image should start along the path. Possible values are:
|
|
Aspect ratio factor |
Stretch or squeeze the current image aspect ratio. |
Channel blending
This section control the blending result for when the path overlaps itself.
|
Parameter |
Description |
|---|---|
|
Alpha |
Control how the Alpha section of the Ribbon path is blended in regions where overlaps iteself, which affects the intensity of the blending of all the other channels. Possible values are:
|
|
Normal |
Define how the Normal channel is blended in regions where the path overlaps itself. Possible values are:
This setting is separate from the Normal blending mode defined for the whole layer, which is applied after the path's own self-overlap blending. Note: this setting is disabled if the channel is a uniform color. It is compatible only with bitmaps and Substance resources. |
|
Height |
Define how the Height channel is blended in regions where the path overlaps itself. Possible values are:
This setting is separate from the Height blending mode defined for the whole layer, which is applied after the path's own self-overlap blending. Note: this setting is disabled if the channel is a uniform color. It is compatible only with bitmaps and Substance resources. |
Example of what the blending mode with the height channel can look like:
Text and non-square images
When using a Text resource or a image with an aspect ratio that isn't square, it will be automatically scaled to properly fit on the Ribbon path.
This behavior make it possible to easily write text or repeat images like trim patterns along a path.
