Why you shouldn’t use a mask for masking …

While helping a bit forum member Tobias in his affords to re-engineer the screen-design of German sportschau (weekly football report) for his 8y old kickers, I realised you can not rotate masks.

From the beginning:
To create a Loupe effect, you simply clone the source, zoom in and ‘cut a hole’ with a mask. Easy.
(Watch attached video)

So, we made a nice little animated graphic, added a circle-mask - easy.

But …. When you rotate the graphics around x (tilt), as in TV, you can not rotate the circle-mask … pitty.


Plan b):





Instead of a circle mask apply an image-mask; here: a circle.
Adding the circle to our animation group allows us:
• Mask and animated graphics perfectly match, even keyframed around the screen
• Zooming in/out the graphic automatically matches the mask.
• Rotating the group rotates the mask too - because it's a graphic…





Tl;dr:
Instead of the mask-tool, consider an image-mask as the more flexible tool for masking.

What if you put it in its own Group, and rotated the Group?

yep, that what comes up first to mind - but doesn't work in this case, have a look, screengrab of the video I attached above:




the zoomed, bigger layer has to stay 'flat'/not rotate, but the 'hole' = mask should change its shape according to some graphic. layer above all that.

at first, the animation and the circle-mask were both linked to some slider ... until I noticed, a circle-mask can only be rotated along z-axis ....

hold on for a second, translating GUI German>>English....

aaaand done: /s. attachement/

meanwhile we added two other features:
an optional drop-shadow and adjustable thickness of the segments … not top of the list on my agenda, but … anyhow.
