I was wondering what parameters/settings I would need to change to do the opposite effect (Making the Mesh appear with the same effect). Ive been trying to do that but I cant seem to get it to work right.

Hi svahos,

The easiest way would be to animate as the tutorial suggest, then export as Alembic [abc] file. When all that is re-imported, the Alembic offers an offset parameter. Set the Offset to the values needed to reverse the animation. IF the file had 90 frames, then the Offset is at frame zero -90 and on end 90. See the example file [01] here.

The Freeze Layer has no shrink (in opposite to Grow) option. This needs an entirely different approach. Since the Grow effect starts from the Spline, it continues until all is 100%. This final position does not need a definition, it is reached automatically. If the reverse is needed, where should it start? This requires some kind of definition (Spline Mask, perhaps?)

Besides, at the moment, I’m not clear if you want the effect precisely in reverse, outside (most significant distance from the Spline) polygons fly in first, then close the area around the Spline, or grow from the Spline?

Cheers

P.S.: without giving too much away from the tutorial, this is a different approach to handle the idea of inverse growing. In other words, starting from the border of an object and grow towards a given Spline path.

This is a sketch, but it contains the information needed.

Project file:
https://www.amazon.com/clouddrive/share/0MSmaAn1vXhd1Wz0IffbgZdHLPSNMVoIWdCb9zUjBcz

In a nutshell: As a base, all information is given to allow the Plain Effector to work (Spline Mask> Inside), to be able to scale in this case.
Please check the tutorial about the use of several Effectors and their information-flow.
Then the fringe/border parts are pulled in (large), and shortly after this, the core parts (Thin) are back as well. It is all just Photoshop layer 101 and animating the elements needed, as discussed in the series.

The best way to practice it is to use a Plane and a Weight-Tag (set to Fields, of course). This will lower the complexity during the exploration.

Awesome! It worked,I did what you initially said and reimported the file as an alembic. I ran into an issue at first but got it to work by adding an XPression to the offset animation to set the driver to absolute while selecting the children in the alembic null.

Thanks!

Hi svahos, thanks a lot for the feedback. You’re very welcome.

I loved to read that you have success with your set up and the extra ideas with Xpresso!

My best wishes
