Changing material parameter, but it does not change material?


I need to use a material in UMG widget and change some of its parameters.
My variable color changes, but the material not, what I’m doing wrong?

My simple material:

I create a material instance from simple material, and UMG Widget with image.

And trying to change variable in my character controller:

You have to set the Material of the image to the one you just created.

Resolved, thank you very much !!)
