Change material parameter in widget Animation

[theGreatDW]

So I just finished the Unreal Fest tutorial here:
# Advanced UI Templating Techniques

in 20:06, there’s a animation bar which control the material parameters there.
But she didn’t told us how to setup that animation to control the material parameters.
And I couldn’t found it in my project.
Although I know other ways to control the parameter in Animation. I really struggle with her approach.
Anyone knows how?

Figured this out!

1. In your UI image, set its brush material to a material instance with a parameter. In my case, I have a material with the scalar parameter “Wipe”

2. Add the Image track to the animation

3. Click the Plus icon then “Brush.Brush Material”
   

   

4. Click the + next to Brush.Brush Material and you should see the names of your parameters there. You can click the one you want and then key frame it.
