Hey,

So I'm having this case where I have 100 variations of a plant in a single file cache, each on a different frame.
I'm trying to scatter them on a ground and I want scatter to randomly use variations of this plant for each point.

I made a setup with a timeshift and for each point, where timeshift frame refers to for each iteration and randomly chooses a variation... at leat I think i did that.



rint(rand(detail("../foreach_begin5_metadata1", "iteration", 0))*20-1)

and it doesn't work. It only scatters one variation.

I figured out that when I change the frame value to:

rint($F + rand(detail("../foreach_begin5_metadata1", "iteration", 0))*20-1)

then it works but then it eats a ton of ram so I guess I'm doing it wrong.

I'm using packed disk primitives by the way.

My frame range is 1000-1100 if this makes a difference.


Please help

try loading all your frames at once using File Merge SOP (as Packed Disk) so that you have 100 packed primitives as a static geo
then you can just copy using Piece attribute on Copy SOP to pick one variant per point, no foreach, no timeshifts
