Can you post pictures of your material and blueprints?
I have a scalar param in my material and I know I have to create a dynamic material instance to change values via blueprint, and if I use Event begin play it works, but it doesn’t work if I use Event tick. Like if I want that value to be a random value in range, and change it over and over.
Material
Material Instance
Blueprint
Basically I’m spawing a lot of cubes in a line create a random color and set the materials color to that random color, that works fine and, and im trying to make the Glow paramater change value every 0.01 seconds and it doesn’t do anything.

You should create dynamic material instance in Begin Play and store it in a variable.
Then you can update it every tick.
As alternative, you can use Material Parameter collection, or randomize the color inside the material itself using Time material expression.
