i would like to do a per shot process based on a CSV file listing all shots and frame range of shots, where i merge all alembics of the shot, then process them (generate a particle sim from the geos or whatever), do a preview render,and finaly write out an Alembic or a bgeo sequence of the result (particle cache for example).
I managed to retreive and merge the alembics per shot with geometry import TOP, then use invoke TOP to process the result in SOP context. But i don't know how to write the result properly with the frame range i retrieved from the CSV per shot (@start, @end).
I tried putting the invoke node in a loop and use the @loopiter to override the “Evaluation Time” parameter but the Invoke node does not cook a t all.
I don't know what to do or test next.
Maybe there is a totaly different approach to achieve this.
I attached my project with the csv.
If you have any clue on this, please help
Thanks a lot.
