I'm looking through Weapon Resource Wad to try and learn some decoreate and I see this

The thing is, last time I saw, all the explosion special effects are done from the death of the main projectile. THis weapon does not do that, instead Projectile and special effect are 2 different actors. The base projectile has no frames wit hthe explosion happening.

And 2 actors are not linked in any way in the decorate, nor in the other file.

Are there any correlation (like automated substitution) between <Actorname> and <ActornameExplosion> actors? If so - it is not documented anywhere. Or is it and I just havent seen it? I don't know WTF is going on here.

Somebody please help.
