foreach on groups

[sanostol]

inside a foreachloopSOP working on groups, is there a way to get the group name that is currently processed?

assuming that your stamp varibles on foreach are set to default

in H11 you can do just:

`stamps("..", "FORVALUE", "")`

it contains group name when working on groups

in H10 you need to use (if I recall correctly that back then FORVALUE variable just contained index)

`arg(primgroupmask(opinputpath("..",0), chs("../groupmask")),stamp("..", "FORVALUE", 0))`

in H11 if you need just index there is variable named FORIDXVALUE by default

hey, that was fast

i tried it but without success. `stamps("..", "FORVALUE", "")` returns nothing here, when set to for each group

i'm using h11

where are you using it?

here is a little scene using it in Font SOP inside foreach

EDIT: of course you need to look at it when outside the foreach, the easiest method is to pin the viewport when outside, then dive inside for modifications and you can see the result in the pinned viewport

yes, it is at first, but it's very useful so it's worth bending your mind a little

just stumbled over this thread,

actually another easy way to access the group name inside a foreach is

`chs("../each1/group")`

cheers,
