Hello, I got issue to change material in Type parameter. Element Set Parameter Value node works for instance parameter. Any idea to change type parameter in family.

You need to feed the actual `Type` and  
not the `Instance` (the placed Family).  
You can tell the difference by  
their ElementId.

However, that being said, there is a node called  
`SetParameterValueTypeOrInstance`  
(I forgot which Package. I guess Clockwork or GeniusLoci) that will probably ‘do the trick’ also.
