hi all ,
please i would like to know if its possible to make change texture to an object by using a click trigger or something like that ! thks a lot
yes, it’s doable. If you check Blueprint_HUD example, you can see how to drive a parameter of a material with variables.
And in blueprint communication, there is a rocket example that changes color, and one that sets wood material to wet or on fire.
Download ContentExamples from market place and you will see them.
thks very much for your answer ! do you think i can find a tutorial im realyu newish with blueprint . thanks very much
