The behaviour of the “for loop” nodes in SOP is confusing. Attached is an example.

I am trying to paint some point parameters (p0, p1, p2). So I use the “for loop” and link the paint “cdname” parameter to the iteration number. But the behaviour is unpredictable.

In the example attached, I switch the order of two nodes (a transform and a paint). The order change should in theory have no effect. But it does, with the left one producing the wrong result. This kind of thing makes it hard to use these nodes, since you never really know if it is going to work or not.

Can anyone explain, or is this a bug?
