Here's the sort of thing I ended up doing:[spoiler][code=php]class TargetPointLight:PointLight{
    override void postbeginplay(){
        super.postbeginplay();
        if(target)setorigin(target.pos,true); //or such position relative to the target as may be appropriate
    }
    override void Tick(){
        if(isfrozen())return;
        if(!target)destroy();
        else setorigin(target.pos,true);
    }
} [/code][/spoiler]though it could also be possible to have an actor inherit from the dynamic light actor (but making sure to call Actor.Tick() in its Tick override)

[quote="Rip and Tear"]Furthermore, because you can't attach ZScript-defined lights to an actor anymore, the DONTLIGHTSELF flag can no longer be used with these lights.[/quote]

This is the biggest downside, IMO

On the other hand, the performance improvement gained from this change was desperately needed. Aaaaa

Previously, it was possible to attach a ZScript-defined dynamic light to an actor with the target pointer, but at some point recently that was removed. There should be some other way of attaching ZScript-defined lights to actors.

Attaching lights is far simpler than manually managing light positions (especially since SetOffset was exposed to ZScript). Furthermore, because you can't attach ZScript-defined lights to an actor anymore, the DONTLIGHTSELF flag can no longer be used with these lights.
