How would I edit a material instance in a task?

I am currently unable to make my enemy character’s blackboard tasks use a dynamic material instance, to change the radius of effect that a material has.

I am trying to set the task to set the material radius to 0 from 120 smoothly, and the opposite, however, I am unable to even set the value from 120 to 0, it doesn’t change values at all.

Is there any way to be able to do this?

After doing some testing I was able to see that the task actually does run the “Set Scalar Parameter Value” node, yet, still no updates on the in-game character that has the material instance set as their material.

I found a far more effective way of going about this effect, by using a “Material Parameter Collection” and this works quite well for getting the effect that I’d like.
