The Jiggle Deformer Options window appears.

See Create Deformers > Jiggle Deformer and Advanced deformer options.

To paint jiggle weights

1. Select the surface with the jiggle deformer you want to paint weights on.
2. Switch to smooth shading mode by selecting Shading > Smooth Shade All or by pressing the default hotkey 5.
3. Select Edit Deformers > Paint Jiggle Weights Tool > .

The Paint Jiggle Weights Tool Settings appear.

Note The Paint Jiggle Weights Tool automatically detects jiggle deformers on the surface.

4. Check that Color Feedback is turned on in the Display section. Color feedback helps you identify the weights on the surface by representing them as grayscale values (smaller values are darker, larger values are lighter).

Tip You can use the default hotkey +c (Linux and Windows) or +c (Mac OS X) to turn Color Feedback on and off outside the Tools Settings Editor.

5. Select the jiggle deformer you want to paint.
6. In the Paint Attributes section of the Tool Settings window, click the jigglen.weights button and select the appropriate jiggle weights name from the pop-up menu.

You can only paint weights on one jiggle deformer at a time. If you select more than one jiggle deformer, you can only paint weights on the active one (the one that provides color feedback).

If the surface has only one jiggle deformer, you can select the surface alone.

Tip If you are painting on a single surface, you can skip step 6 and select the jiggle deformer and weight attribute without opening the Tool Settings window by -clicking the surface and selecting the appropriate jiggle weights name from the Paint command submenu.

7. Select a brush, paint operation, and value and define other settings as required.
8. Drag the brush across the deformer where you want to change the weights.

Tip Using hotkeys, you can quickly pick weight values from one jiggle deformer and paint them on another jiggle deformer or the same one. Do the following: Select the jiggle deformer with the weight values you want to pick. Hold down the Pick Color Mode hotkey (default hotkey: /), click on the area of the jiggle deformer with the weight you want to pick, then release the hotkey. If you are painting the picked weight on the same deformer, drag the brush across the deformer. If you are painting the picked weight on another jiggle deformer, select that deformer, then drag the brush across it.

To create disk cache for jiggle deformers

1. Select Create Deformers > Jiggle Disk Cache > .
2. The Jiggle Disk Cache Options window appears.
3. Click the Basic and Advanced tabs and set the creation options.

See Create Deformers > Jiggle Disk Cache and Advanced deformer options.

4. Do one of the following:
• Click Create to create the jiggle cache. The options window closes.

Maya creates the jiggle cache and creates a permanent jiggle cache file for each jiggle deformer in the scene. The file or files are in the current project’s data folder, and are named scene_jigglen.mcj.

• Click Save to save the creation options without creating the jiggle cache. The options window remains open.
• Click Reset to reset the options to their defaults. The options window remains open.
• Click Close to close the window.
