Reported it to Epic Games but posting it here too so it might not get lost that easily.
- Create new shader
- Create any node in it (for example just scalar value (1))
- Select that node, right mouse click and “Collapse nodes”
- Inside collapsed nodes try one of two things:
- create component mask with Shift-C hotkey
- create Vector4 Parameter (hotkey 4 / ConstantVector), right click it and hit “Convert to Parameter”
Results:
the component mask or Vector4 Parameter will be created in the main shader graph, not inside the collapsed node
Expected:
expected them to be created in the collapsed node graph too
