Resizing groups with paths

[nina_paley]

1. Frame zero. The snake follows that path. The paths are animated by the bones of the body.


2. The animation works just fine. The body has a second, masked layer that makes the snake look like its twining around.


3. But if I resize the whole group, the snake no longer directly follows the path, but rather follows some strangely resized path I can't see. You can now see the masked body layer obscuring the snake incorrectly. Also the snake gets shortened. I resized the whole group and the body and its mask layers resize consistently, but the snake on the path gets all tweaked.


How can I control this? I want to be able to resize these layers after I animate them. I know I can use the camera but sometimes I have two groups with path animation I want to resize independently of each other.

what exactly is the setup you have?

I've tried a simple structure
group
>> snake
>> path
>> mask
>> body

and that works fine when I scale group.

A couple of things to check:

- are the bones deforming the mask in an "unexpected" way?
- if snake is now offset from path - have you moved the snake layer? I think there's a "feature" in Moho that means it can't cope with a layer that is following a path that also gets moved...

Tedious, but first thing to check: do all layers have the same Z value?

(Wouldn't that be great to have as a script? "Set all Z values of all layers to 0?")

Z values are the same, I checked those first.

What I discovered after some discussion on Facebook's Moho Pros group, is that if I put the snake in the same bone layer as the path (which is guided by the body bones), the problem is corrected. That means I can't have the snake in its own bone layer, which I had before, because I moved the snake's mouth with bones. Not ideal, but manageable.
