[danieljones]

You're great at explaining these concepts--thanks for making this!

[alexandr_kd]

Thank you. Turned out really useful thing.
Didn't know how to use this in materails, because this strange input form.

[madmodder]

Yes! this is just what I was looking for, thanks.

I wish there was a C++ variable to BP Node conversion table, coming from Java to UE4 was kind of annoying

[maximilianhohl]

Thank you so much for this! You are a great teacher.

your intro has the same bpm as Summertime by Childish Gambino

[nonpurplestar]

Thank you for the explanation Mathew_!!
But what about when there are two conditions like 0 <= X <= 100
Thanks in advance_!!

[davehansan]

Is there a way of softening the transition after an if node?

[mindped]

in terms of performance... does it have to do the math for both < or > input? If it only uses one....
