Hello Jacky and thank you so much for your response. I recorded a video to explain better:
I think you are the one who understood better my problem, but I’m pretty new in UE and I can’t catch well your explanation. I followed a tutorial to make my material and, without the timeline, it doesn’t work (I’ve just tried); I’ll post screens to let you see how it works (it uses a material parameter collection, I can’t understand well why). About the reset, this is just my problem. Could you explain me step by step or give me some references about? I don’t know what else to do.
