Hi I am trying to blend-shape between 2 files on disk with pdg and output some variations of the blend.
Is there a way write something like `@pdg_index` in one file loader and and `@pdg_index +1` in the other file loader so that i always load the next file on the second file loader ?
Many Thanks

you can append Partition By Range to group each frame with next frame
Upstream Range: 2
Partition Range: 2

essentially partition 0 will group frame 0 and 1
partition 1 will group frame 1 and 2
etc.

any workitem that depends on any of those partitions will be able to access both files through `@pdg_index.0`and `@pdg_index.1`
