Moho Animation Forum

Hi,
Am I missing something? I have a layer with a circle in it and I want to use squash and stretch. I should be able to grab one of the top or side handles with the transform tool and ALT and maintain the volume of the object. This isn't working for me and the volume of the object increases? Anyone any ideas other than manually changing the x and y scales? Thanx.

Could be several things...

the placing of the origin point is a referent point
curvature is not re-calculated but adjusted if not entirely preserved

... and above all, deformation as described, it's proportional and 'generic' transformation not exactly the same as s&s within Bone cons. pannel (which is also 'generic')

manual is wrong .. it's shift (not alt) with one of the edge bounding box control points selected to scale a layer preserving volume (although as Maestral points out, it's actually keeping layer_scale_x * layer_scale_y constant, not actually preserving shape area.)

Select transform tool, grab side/middle handle (NOT corner handle), press alt, drag.
Shift seems to do nothing (in v11.5).

In v12, alt is uniform scaling.

Here's the list of Transform Shape shortcuts that work for me in Moho 12.5:

- Drag from corner, scales non-uniformly from opposite corner.
- Press Alt while dragging from corner, scales uniformly from center.
- Press Alt and then Shift while dragging from corner, scales non-uniformly from center.

- Drag from side, scales non-uniformly from opposite side.
- Press Alt just while dragging from side, scales symmetrically from center.
- Press Alt and then Shift while dragging from side, scales while maintaining volume (i.e., squash and stretch.)

Hope this helps.

Note that Transform Layer behaves differently:

- Drag from corner, scales uniformly from origin
- Drag from side, scales symmetrically from origin
- Press Shift while dragging from corner, scales non-uniformly from origin
- Press Shift while dragging side maintains volume (i.e., squash and stretch.)

With layers, you can't scale from the opposite corner or side because a layer always scales from its origin. So, by default, it may appear to scale from center (assuming your shape is centered,) but if you move the origin, the layer will scale from the new origin position.

Or...

You can bind the shape or layer to a bone and use the bone to give it a 'squash and stretch' effect.

To do this, select the Bone with the Select Bone tool and then open the Bone Constraints panel. Next, enable Squash And Stretch Scaling. To see the effect, you need to be on an animation frame (not frame zero.) In this case, the scaling occurs from the base of the bone.
