Another Grow Bounds question
on Oct 24, 2010 at 8:10:46 pm

I have watched the Grow Bounds tutorial and looked in the archives of this forum to answer my question, but unsuccessfully.
I understand that the Grow Bounds effect must be at the top of the stack of my other effects, but how does this apply to a group of compositions that have been pre-composed? Does it matter? I am creating a Spinning Orb and want to scale down the composition over another layer of footage, but am having no luck getting the effect to work.
Thanks.

"I am creating a Spinning Orb and want to scale down the composition over another layer of footage, but am having no luck getting the effect to work."

I guess I don't understand how doing that has anything to do with the Grow Bounds effect. Can you elaborate?

Yes. When I scale the orb comp down over the footage, you can see the rectangular boundaries of the comp. I want to expand the edges of the orb composition to the edges of the layer beneath.

Grow bounds does not make a composition larger. It merely makes the work area of a layer larger when applying effects (such as Shine) that work on a layer's bounding area.
You will need to make the composition size of your precomp bigger.

you could try using motion tile or cc repetile to increase the layer/precomp size. both those effects will tile the layer they are applied to.

motion tile will just repeat or mirror the layer, repetile has several options for repeating the layer, along with a blend option that will feather the edges to help blend the edges.

Ah-- that works! Seems obvious now.
Thanks, Mike!

Another option is to enable the Collapse transformations switch for your precomp layer.
