neil_math_compHello! I tried using you method but it doesn't work. Basically what I want to do is place small spheres (like bubbles) inside my animated spheres that merges at the end, pretty simple but I haven't found a really straightforward solution to my problem
Just two simple things:
1) (optional due to 2) The Copy SOP isn't copying over sourceprim or sourceprimuv from the template points. You can fix that by turning on the "Use Template Point Attributes" toggle on the Copy SOP.
2) Because each box has 8 points and P is being interpolated based on a single point for all 8, each box will have its 8 points moved to a single position. To fix this, put the Scatter into the first input of the Attribute Interpolate, then copy the boxes to those points afterward.
Hopefully that's what you were looking for!
If you also need to avoid any possible rotating of the box orientations around N, you can add an "up" attribute, so that the boxes will be copied in a way that uses N and up to determine the orientation, instead of just N. It'd need to be animated with the geometry, though, so it could be difficult if you need it; there might be some way to do it with PolyFrame.

EnivobWhat if the input is an animated alembic? how can I do that? the file won't work and I tried modifying it, please
Try a different random seed on the scatter. And don't slam it to the floor so much..? Solve for the shot, not for the science.

That's not true, I did use read_alembic, and it need to be set up specially for maya, if not it won't load. Once you've managed to load the alembic and its points, it will be useless because Vray and Redshift won't render the instances, only arnold does it. So, don't bother and don't waste time, use Blender (free and open source)and it will deal with the points and instances as usual.
