Anim Curves

AnimCurvesAlone.png

The Anim Curves panel displays curve values for Morph Target, Attribute, and Material curves for your project. You can delete and rename curves here, as well as preview curve data. You can filter the visible curves to show only active curves by clicking on All Curves to deselect it, which also enables you to filter by Morph Target, Attribute, and Material curves with checkboxes. In addition, you can define Material Curves which allow you to drive Material Parameters or Morph Curves (if Morph Targets exist within the associated animation).

To open the Anim Curves panel in either the Skeleton Editor or Animation Editor:

  • Click on the Window menu, then select Anim Curves from the dropdown menu.

By default, as you play an animation back, the curve values will update along with the playback. In the image below, curves for L_smile_pose and R_smile_pose are being used to create a smile on the face mesh. The values of these curves are shown in the Anim Curves panel at the current point in the animation (where the full smile is achieved by being weighted at 1.0 when reaching the end of the animation).

If you uncheck the Auto checkbox for a particular curve, it will no longer pull data from the curve. This allows you to selectively turn off the influence of a curve and preview the result. You can also enter a value manually or by clicking and dragging on the Weight field. In the below image, the L_brow_up_pose curve value has been manually set to 1.0. You can see the effect in the viewport, as the left eyebrow of the face is raised all the way.

  3. Press Enter to save your new name.

This adds a curve to the current skeleton, but you will need to then add the curve and set its information in the Animation Editor to determine what the curve affects.

To delete a curve:

  1. Right-click on the curve and select Delete from the dropdown menu.

    If the curve is currently being used by any assets in your project, a confirmation window will appear warning you that the curves will be removed from those assets.

  2. Click Yes to continue with the deletion, or No to cancel.
