I want to do a simple merge of some algorithm outputs in QGIS graphical modeler (not for an iterative process, like my previous question "Collect results of iterative processes in QGIS graphical modeler", but just for two outputs of parallel/forked extractions).
I feel like this is so basic, it should be obvious: Right where it says
'Input layers' I ought to be able to select multiple inputs, but choosing "algorithm-output" gives me only one pulldown menu.
How do I connect two outputs as input layers (as indicated in yellow)?
I tried using
'Expression' as Input, and there I can select output layers as variables (e.g.
@outputX). However I don't know how to use this expression to use multiple variables, either (e.g.
@outputX, @outputY gives an error:
Unexpected COMMA where $end was expected
other variations don't work as well, e.g. with space, semi-colon, ...).
