Use Motif to create a tiled symmetrical texture.
You can access the Motif effect in the following ways:
- As a Batch node. This node accepts a front clip and a matte clip, and outputs a result and output matte clip.
- From the EditDesk. Select Flame FX2 from the A/V Tools box and then click Motif. You can select Front or Front/Matte from the Input Mode box.
Source clips can be transformed before symmetrical effects are applied. Transformations are applied to both the front and matte clips simultaneously. You can select the type of symmetry mode to use on the transformation, and define its parameters.
The radial symmetry mode displays a user-defined widget, which is a polygon with an equal number of sectors to the order of symmetry. You select the sector to use as the originating tile, the basis for a kaleidoscopic texture. Additional parameters allow you to define the center of symmetry of the image, and the angle and radius of the originating tile.
Front and Result views in radial symmetry mode
In Radial mode, you can also reuse the pixel on the edge of a sector to pad the space between outer tiles.
Result views with the repeating disabled and enabled
The region of interest (ROI) effect uses a user-defined rectangular or triangular selection as the originating tile to create a basic mirrored texture.

The Motif menu displays 2D Texture Transform controls that allow you to simultaneously change the position, scaling, rotation, and the type of image padding. The Symmetry Mode controls display a colour pot for the original tile selection.
- X and Y Position fields
Display the number of pixels by which the input and matte clips are offset.
- X and Y Scale fields
Display the percentage of horizontal and vertical scaling to apply to the front and matte clips.
- Scaling proportional button
Enable this button to effect the Scale X and Scale Y proportionally.
- Rotation field
Displays the angle of rotation of the front and matte clips.
- Repeat button
Provides fill options to pad the empty portions of the frame with the last line of pixels, a repeated (rolled) image, or black pixels.
- Symmetry Mode button
Determines the type of symmetry effect to apply to the transformation.
- ROI Mode button
Select between a square or triangle region of interest mode.
- Order field
Displays the order of symmetry. It also indicates the number of sectors or sides of the polygonal widget. An order of 2 creates a basic mirrored image. An order of symmetry can have an odd number as a value. Tiles are mirrored in a counter-clockwise direction, therefore the sector to the right of the highlighted sector may not be its mirror image. Displayed in Radial mode.
- Even button
Enable to maintain an even order of symmetry. If the order of symmetry is an odd value, an extra tile will be added, ensuring that adjacent tiles are mirror images of each other. Displayed in Radial mode.
- Angle field
Displays the angle of the axis of symmetry. Displayed in Radial mode.
- Radius field
Displays the pixel length of the sector radius. Displayed in Radial mode.
- Edge Repeat button
Enable to use the pixel colour on the sectors’ edge to pad the space between outer tiles. Displayed in Radial mode.
- X and Y Centre Position fields
Displays the horizontal and vertical position of the centre of symmetry.
- X and Y ROI Scale fields
Displays the horizontal and vertical dimensions of the region of interest as a percentage of the original dimensions of the clip. Displayed in Region of Interest (ROI) mode.
- Proportional button
Enable to effect Scale X and Scale Y proportionally.
- Softness field
Displays the amount by which the motif effect is out of focus. Editable.
- Show Widgets button
Enable to display the widgets in the clip.
- Widget colour pot
Displays the colour used to highlight the originating tile.
Modifications to the originating tile and symmetry mode parameters can be made gesturally in any view.
