 So you want the players to be able to edit custom color schemes, not a problem. Let's say you have three sliders in your UI, one for red, green and blue values. First, you have to create a blueprint for the actor you want to change the color of. Just add a mesh for the character. For this video, let's just assume the character is a cube and we will assign it a material instance that already has parameters for a color value. Now in the event graph, drag out a dynamic material instance and promote it to a variable. Name it whatever you want, set this to the material name your actor is using and then create a new custom event. I'm just going to call it update color and add the color value input and make sure the input value is set to the type linear color. Drag out the dynamic material variable from here. Drag out a set vector parameter value then connect them like so. Now make sure the name that goes here is the exact same name as the parameter value. Then in the blueprint graph area where you have your UI sliders, do your standard value change triggers. Drag out a get actor of class and set it to your character blueprint from earlier. Drag that into the update color event you created in the blueprint then connect them like so. Make a color note and connect your slider UI values like so. You're done. Hope that helps and as always, we'll give a fantastic day and I'll see you around.
