So the problem I’m having is just how to get all that into my BP. The material with parameters is mapped to a static mesh (SM_Essence_LightKit). The widget is named “controls”. I already have the “close” button set up (thanks to one of your earlier solutions!), but I’m going to ideally set on/off button, and temp and intensity sliders. I don’t understand where the functionality for the sliders would fit into my current BP, or if I need to cast to the widget each time. I’ve attached some screenshots for context - any advice would help (again!). Thanks so much!!
