How to change custom attack projectile art?

[tranquanfr1988]

I have just download 2 interesting model files
* Tank M1A2Abrams : M1A2 Abrams

* explosion: Explosion Big
https://www.hiveworkshop.com/data/ratory-images/29/29921-d5c2dcf92687d91165b8446b4455bd85.jpg

And I want when tank attack a target, the explosion will appear in this without bullets (because bullet fly so fast, we can't see it).

In this case, I use Unit Human/Mortar team. In Object Editor/Units, I can change Art-model file by model tank M1A2Abrams but Combat-attack-projectile art, I can't import model explosion and can't make a attack-projectile art as I want.

Can you help me make a attack projectile art as I want, thank so much?

if you don't use orbs or crits or bashes, you can go with attack orb-effect which would place, for instance, a slow for 0.02 s. setup this slow to use proper blast effect as target effect. then everytime shot connected slow will go on and play it's animation of blast
