Not sure if I got it right, but it seems to be somewhat similar to the thing in the other thread:
-
material
-
actor
-
widget:
-
the dispatcher you previously asked asked about; the inputs here are important (int & material interface object):
In short:
- actor with a widget component
- the widget creates a Material Instance Dynamic and sets it on the owning actor’s static mesh via a single dispatcher call
- slider updates the texture in the material
Hope that’s close enough. Do tell if there’s anything confusing here or I completely missed the mark! I can zip the project and push it your way if that’s of any help all.
