Aniamte vector or scalar parameter Material.

Hi. I’m a little confused, I follow this tutorial

And the animation never happens, the blueprint is fine, I created the key with different values, I connect the material and assign the correct parameter, but when I play and enter in the trigger box nothing happens.

thanks.

I found the solution (Dynamic Material Instance), but another question: is possible use a Matine to animate a scalar or vector parameter in a material?, if isn’t, why in the matine appear this option?. Thx.
