How to you combine weapon with its slashing effect?

[Gidz Cross]

For some unknown reason the slashing effect is somehow being ignored by my client. I wish to learn on how to combine the sprite with its slashing effect. I have the resources here. How do you do this on actor? Thanks!

Turns out if you use hight class num the slashing effect will get ignored (at least for my 2018 client). The solution is to combine the those custom weapon you have with its slashing effect.
