Create Dynamic Material Instance node. From the context menu, select the first option,
which is Promote to a Variable ; this will add a variable to the left-panel list. Feel free to
give it a name you can recognize, which, in my case, is thisColor . Now, the whole thing
should look like this:
Now that you've created the dynamic material instance, you need to set the new color for
it. To do this, you need to go back to the event graph and start adding the logic for it. I'll
add it to the ball also, and you need to apply it again in Event Graph of the platform
blueprint.
Add an Event Begin Play node, which is responsible for the execution of some procedur-
als when the game starts. Drag a wire out of it and select the Set Vector Parameter Value
node that is responsible for setting the value for the material.
Now, add a reference for the thisColor variable and connect it to Target of the Set Vector
Parameter Value node. Last but not least, enter Parameter name that you used to build
the material, which, in my case, is BaseColor .
Finally, set Value to a color you like; I picked yellow for the ball. Which color would you
like to pick?
