so, timeshifts and for loops
kindasorta got a definitive answer
“The For Each Begin SOP does not do an implicit blast on it’s input unlike the Each SOP that was there in previous releases. If you put a Time Shift SOP before the Fetch, it will seem like it is not working as the Fetch isn’t cooking it’s input. It will return the same piece of geometry for all time. To correct this, use a Blast SOP and delete out the piece you want with detail expressions pointing to a Meta Data SOP.” – Jeff Lait
More explicitly, don’t let the begin block split your geo for you. Change it to ‘fetch input’, so it brings in everything on each run of the loop, then manually isolate to the thing you want, by using info from the metadata sop. Now any timeshifts within the loop will behave.
