Hey! VOP has only Switch node, but it has single output.

My situation, then inside Foreach loop, sometimes I get wrong result, so I need to branch to either perform additional nodes, or go directly to loop end and cointinue looping.

VOP has no if_then node, if_else, or _branch or anything similar with multiple outputs based on condition.

Any idea to workaround that?

you don't need more outputs for Switch VOP, it simply switches between False (0) and True (1) inputs or if you want even more inputs
the downside is that all of them get evaluated before switching

so alternatively
use If Block

also this can help:

I'm not at work so I can't verify but, did you have a look at this? http://www.sidefx.com/docs/houdini/nodes/vop/if.html [www.sidefx.com]

Maybe I used wrong terminology, and I am inside SOP, not VOP, as all I have is switch node only.

In yhat case Switch is all you need

It will switch to yhe branch you want so if you put your condition to the Input parm it will execute first stream when false (0) and second stream when true (1)

Yes, but there is scenario, when I don't need any of inputs and just want to exit the loop, i.e. output should go directly to loop end. Hmmm, but maybe you are right, seems like I need somehow fully redo my node tree to accommodate switch usage

This is because sometimes both inputs are empty, and houdini hangs up in infinite loop. So I wanted to have several outputs to get out of this situation.

to get out of For Loop SOP earlier you can use Stop Condition parm on Block End SOP
