applying a bulge effect to a 3d space?
Please help me,
I have made some bubbles that I want to fly towards the camera out of the sea I have placed them in a 3d space but I want to apply a bulge effect below each bubble so it distorts the background behind it.
This works fine in 2d space but when I try and pickwip the centre of the bulge to the bubble there is only x and y co-ordinates available for the bulge, even though the 3d option is activated and I can’t seem to get it to co-ordinate and move in sync with the bubble.
I have no idea if I am moking this over complicated, it has taken quite a lot of messing so far to get the rest of it to work, is it possible to use the bulge effect on a 3d object that changes size as it moves towards the camera? Please please help if you know the answer! many many thanks! x

There may be a way to apply multiple instances of the bulge effect to a series of points, but that’s beyond my ‘off-the-top-of-my-head’ skills.
However, if that doesn’t pan out, you could always try faking it a bit by precomping your 3D bubble layer, then in your new comp have the precomp’d bubbles, your background, and a duplicate layer of your precomp that you’ve turned into a greyscale image*. Then, you could add a displacement map to the bubble layer (specifying your greyscale version as your distortion layer), turn off visibility of the greyscale version, and maybe add a slight bit of compound blur to your bubble layer as well if desired. It’s not accurate, but I guess neither was bulge. As long as it looks good…

*You don’t really need to make it greyscale, but it may help you visualize what will affect the distortion. Add adjustments to it until it has enough grey range to make your distortion work. (contrast, curves, etc. Whatever works.)
