Hi，dear guys！
I am confused about the setting of variable parameters in hb constructions. Is there anybody can help me, show some cases or usages. Many thanks!!
Hi @Gao As I know ,the original version of this componet has not the code x and y input. And the construction should be a stable definition, not variable definition.

@minggangyin is right. This component has changed from the Legacy version to now accept a list of materials instead of requiring you to specify each material as a separate variable parameter. If you want to recreate something like the old workflow, you can use a native Grasshopper [Merge][(Merge - Grasshopper Sets - Component for Grasshopper | Grasshopper Docs) component to merge several material layers in a particular order into one list.
