How do you use the total number of primitive groups in a parameter? I have 7 primitive groups created by the Partition SOP and want to use that to drive the number of material created by a Material SOP.

I was thinking it would be a $NUMGRPS or numgroups(“..”) or something similar…

Thanks!

you can use
primgrouplist() - to get space separeated list of prim groups
or
primgroupmask() - to get space separated list of prim groups by pattern

then argc() - will give you number of elements in that list

so
argc(primgroupmask(opinputpath(“.”,0), “grp*”) )
will give you number of groups matching grp* pattern from the first input, etc.

Thanks Tomas, worked like a charm.
