Our project structure doesn’t work with this function:
FranticParticles.MakePartitionFilename
Our Folderstructure goes something like: S:\project_TEST\Render\Sc001\S0001.00\FX\Caches
FranticParticles.MakePartitionFilename will create
S:\project_TEST\Render\Sc001\S_part1of3_0001.00\FX\Caches\v01\particles2_
I went ahead and created a quick fn that doesn’t look for a substring of 000, and just appends to the end of the sequence and it seems to work fine for me, but figured it should be fixed regardless.
Another good reason for scripted gui – though it’d be nice if I could’ve just rewritten MakePartitionFilename 
Thanks!
