Help with Vector parameters

Hi I’m basically awful at unreal bc I’m studying art but it is mandatory in my course to do some of everything, I need to code it so that like all of the cubes in like a specific group I can change the color of easily. I’m following a guide on how to do this from my tutor but am stuck at this section that I cannot find an answer for anywhere where the set vector parameters are different?? and the target for my tutor’s example is the material instance dynamic when I can’t find that anywhere on unreal or make sense of how you add it in the first place, if I could have any advice on how to do this I’d appreciate it a lot. The dynamic material array won’t link at all to the set vector parameter I have when it worked for my tutor and I’m seriously lost, thank you if you can help :slight_smile:

Hey there @Cuida_Tu_Mundo! Welcome to the community! If possible, can we see the blueprint setup and use case a bit more? As it sounds like you want to set a Vector parameter for each instance in the array.
