Bounding box restrictions
I am extremely new to After Effects, using CS3. Its sort of a trial by fire as a client we work for needed motion graphics, and we offered, so yeah…
Anyways, I am currently having issues with the bounding box on imported elements cutting off effects. More specifically the logo I imported (a photoshop file) is having a Trapcode shine effect applied, but as the light passes over, its glow is clipped at the bounding box of the element. I cannot extend the box without extending the size of the file. Im sure there is an easy answer, I just don’t have it.
Thanks in advance for help. THere will undoubtedly be more questions..d.

Try placing your effects on an adjustment layer above the layers you would like to affect.
Choose Layer>New>Adjustment Layer to create one. -
Many effects don’t render outside the area of the layer by default. Sometimes there is a checkbox or drop down menu you can use to tell the effect to ‘resize layer’ or ‘expand output.’ There’s no real standardized way that the effects express this function, so you might have to hunt for it, or the effect you’re using may not even have that functionality!
If you can’t tell the effect to ignore the layer boundaries, then you can try applying a Utility > Grow Bounds effect before the effect you’re trying to work with.
You can also try pre-composing the layer (read up on this in the help, F1) and applying the effect to the pre-comp.
Or for some effects you can use an Adjustment Layer, but note that if you use Shine on an Adjustment Layer it will affect every layer beneath it, meaning the layer you want to Shine may not be the only thing Shining…

I use a simple cheat to get around this problem: Add a rectangle mask to the layer, but delete two points so only a line (connecting the 2 remaining points) remains. As you extend this line, the bounding box will extend with it, while leaving your layer unaffected.
