How to Fade In decal on trigger?

Ahh, thanks for the heads up about the “duo” Set scalar parameter value. Would’ve never guessed about that.

I have one last problem: My target of Set Scalar Parameter Value seems to only link with Return Value from Create Dynamic Material Instance, but it keeps returning an error on log. Do I have to create another Create Dynamic Material Instance after the Set Scalar Parameter Value?

Btw, appreciate the patience =)
