Hi, i’m trying to put random materials on panels, bt i have an error at the end of the script each time, i don’t understand the problem the problem

here’s the script that i did

Did you look at the error? There is no parameter with that name. Either it’s misspelled (parameters are case sensitive) or it’s a type parameter not available to the element instances.

Hi, i found the solution, i had to create a new panel family and add a new parameter to the existing native “Material” and now it works just fine ! Thank you!
