Issue with Dynamic Material Instance

[SinonScarleto (Jalal Mawla)]

Hello All,

I was learning few lessons about UE4 and I had some issues while creating dynamic material for a specific chair.

now what I was trying to create is that color of the chair will randomly change when the player enters that specific area around the chair, which is specified by a box, so as you can see I’m trying to make something very simple yet it doesn’t work when I play the level and I’m not receiving any error msgs about what I did, so I was wondering if I’m missing something in my nodes or do I need any supportive program for UE4 to make this works?
I will attach 2 pictures for my event graph and script, so hopefully it will make things clear if I’m missing something even though I’m sure nothing is missing as I followed a specific tutorial step by step

You need to set the parameter name:

You also didn’t specify the material.

I fixed the parameter name and I named it to seatcolor but the problem remain the same and nothing is changed when I play it

so for the next part, what do you mean I didn’t specify the material if I may ask
